Importance Of Computer Essay - 100, 200, 500 Words

A computer is a modern and complex machine, adequate for performing various tasks in a fraction of a second. These devices are used in various fields such as educational and medical fields. In the education field, a computer is used for teaching and learning purposes. In the modern era, a computer is used for smart classes (computer-based learning) to make sessions informative, and interactive and to ensure that students capture and understand the significant information of all the topics and it does not skip their mind. Various prominent software has been developed to enhance the learning and skills of students and teachers. Computers are used in medical sectors for X-rays, CT scans, MRI scans, etc, to monitor and store the records of patients.

Technology has changed the aspects of life and has made life better. Computers are popular electronic devices that can be used to write documents, play games, send an email, make presentations and designs and browse the internet for finding information. The older generation systems were less effective and had fewer functions but improvisations have been made to make these systems effective and more useful. Computers have made life easy for individuals as one can find information about anything they are looking for at their own pace.

These are used in various places like colleges, schools, hospitals, universities, homes, offices, banks, government organisations, airports, railways, etc. These systems help in communication, storage of data, learning and improving skills, etc. Manual labour has been reduced because of the various software available on computers. This software helps in the calculation, making presentations, writing, online shopping, printing materials, booking tickets, etc.

Nowadays, most activities like traffic control, movement of people in societies, etc. are monitored by computers. High-performance computers are used in the field of Science and Engineering to stimulate dynamic processes, topographic images, plotting and analysing data, and for research and development. They are also used to digitise photographs, make animations and graphic designing, dance, arts, and culture.

Computers have become an essential part of modern lives. These systems serve as a convenient information source for managing organisations and accomplishing various tasks. This is one of the significant reasons that computers are in higher demand for banking, entertainment, education, businesses, administration work, and in industries. The computer generation and delivery market are thriving across the world. From large computer systems to handy systems (laptops); computers are present in all organisations. No organisation, industry, or business can function independently of these systems. They are used for various purposes in different sectors.

Use of Computers in Different Sectors

Computers are used in businesses of small and large scale to store data. It helps business owners to record their company data, information, and salaries of employees, and to allow the work to employees. Different software available in the systems also helps them to store the progress of the employees. They are being extensively used for educational purposes.

Computers have replaced books as large amounts of information and knowledge is widely available via the internet. The present generation (generation Z) is completely dependent on these systems for their educational purposes. Schools, institutes, and universities are dependent on computers to store the information, record, and progress of students. Computer-based learning has been introduced in schools. Educational organisations have also introduced computers as a subject to educate students about emerging technology.

The invention of these systems has also generated employment and a whole sector is dedicated to these systems, that is the IT (Information Technology) sector.

Computer use is not limited to these sectors but also expands to governmental organisations, home, and medical sectors. Computers are used in the medical sector to monitor patients' blood pressure and respiration rates. It helps in storing medical and patient data to deliver quality health care. This information is useful to improve the treatment of the patient. The data stored in systems of medical care units can help in the analysis of disease and control it before it turns out to be epidemic. Nowadays, computer-assisted surgery has been introduced in hospitals, which has become a blessing.

In the government sector, it is used for data processing, maintaining the data of citizens like their birth, location, number of family members, and death. The defence organisation of countries has benefited from these systems for satellites, missile development, rocket launches, etc. Computers are also being used for banking purposes. The use of computers has introduced paperless eco-friendly systems.

The Pandemic Period

None of us can ever forget the lockdown period when COVID-19 cases were rising rapidly, we were locked in our houses and no sector was working except the medical sector. During these times we understood the importance of computers in our lives because these systems helped us to connect not only to our loved ones but also to our colleagues and to continue working with the help of our computer systems. The lockdown period showed the importance of these systems to humankind and it turned out to be a blessing in the middle of chaos. Most companies and educational sectors became dependent on these systems to function properly.

How to Write the “Why Computer Science?” Essay

What’s covered:, what is the purpose of the “why computer science” essay, elements of a good computer science essay, computer science essay example, where to get your essay edited.

You will encounter many essay prompts as you start applying to schools, but if you are intent on majoring in computer science or a related field, you will come across the “ Why Computer Science? ” essay archetype. It’s important that you know the importance behind this prompt and what constitutes a good response in order to make your essay stand out.

For more information on writing essays, check out CollegeVine’s extensive essay guides that include everything from general tips, to essay examples, to essay breakdowns that will help you write the essays for over 100 schools.

Colleges ask you to write a “ Why Computer Science? ” essay so you may communicate your passion for computer science, and demonstrate how it aligns with your personal and professional goals. Admissions committees want to see that you have a deep interest and commitment to the field, and that you have a vision for how a degree in computer science will propel your future aspirations.

The essay provides an opportunity to distinguish yourself from other applicants. It’s your chance to showcase your understanding of the discipline, your experiences that sparked or deepened your interest in the field, and your ambitions for future study and career. You can detail how a computer science degree will equip you with the skills and knowledge you need to make a meaningful contribution in this rapidly evolving field.

A well-crafted “ Why Computer Science? ” essay not only convinces the admissions committee of your enthusiasm and commitment to computer science, but also provides a glimpse of your ability to think critically, solve problems, and communicate effectively—essential skills for a  computer scientist.

The essay also gives you an opportunity to demonstrate your understanding of the specific computer science program at the college or university you are applying to. You can discuss how the program’s resources, faculty, curriculum, and culture align with your academic interests and career goals. A strong “ Why Computer Science? ” essay shows that you have done your research, and that you are applying to the program not just because you want to study computer science, but because you believe that this particular program is the best fit for you.

Writing an effective “ Why Computer Science ?” essay often requires a blend of two popular college essay archetypes: “ Why This Major? ” and “ Why This College? “.

Explain “Why This Major?”

The “ Why This Major? ” essay is an opportunity for you to dig deep into your motivations and passions for studying Computer Science. It’s about sharing your ‘origin story’ of how your interest in Computer Science took root and blossomed. This part of your essay could recount an early experience with coding, a compelling Computer Science class you took, or a personal project that sparked your fascination.

What was the journey that led you to this major? Was it a particular incident, or did your interest evolve over time? Did you participate in related activities, like coding clubs, online courses, hackathons, or internships?

Importantly, this essay should also shed light on your future aspirations. How does your interest in Computer Science connect to your career goals? What kind of problems do you hope to solve with your degree?

The key for a strong “ Why This Major? ” essay is to make the reader understand your connection to the subject. This is done through explaining your fascination and love for computer science. What emotions do you feel when you are coding? How does it make you feel when you figure out the solution after hours of trying? What aspects of your personality shine when you are coding? 

By addressing these questions, you can effectively demonstrate a deep, personal, and genuine connection with the major.

Emphasize “Why This College?”

The “ Why This College? ” component of the essay demonstrates your understanding of the specific university and its Computer Science program. This is where you show that you’ve done your homework about the college, and you know what resources it has to support your academic journey.

What unique opportunities does the university offer for Computer Science students? Are there particular courses, professors, research opportunities, or clubs that align with your interests? Perhaps there’s a study abroad program or an industry partnership that could give you a unique learning experience. Maybe the university has a particular teaching methodology that resonates with you.

Also, think about the larger university community. What aspects of the campus culture, community, location, or extracurricular opportunities enhance your interest in this college? Remember, this is not about general praises but about specific features that align with your goals. How will these resources and opportunities help you explore your interests further and achieve your career goals? How does the university’s vision and mission resonate with your own values and career aspirations?

It’s important when discussing the school’s resources that you always draw a connection between the opportunity and yourself. For example, don’t tell us you want to work with X professor because of their work pioneering regenerative AI. Go a step further and say because of your goal to develop AI surgeons for remote communities, learning how to strengthen AI feedback loops from X professor would bring you one step closer to achieving your dream.

By articulating your thoughts on these aspects, you demonstrate a strong alignment between the college and your academic goals, enhancing your appeal as a prospective student.

Demonstrate a Deep Understanding of Computer Science

As with a traditional “ Why This Major? ” essay, you must exhibit a deep and clear understanding of computer science. Discuss specific areas within the field that pique your interest and why. This could range from artificial intelligence to software development, or from data science to cybersecurity. 

What’s important is to not just boast and say “ I have a strong grasp on cybersecurity ”, but instead use your knowledge to show your readers your passion: “ After being bombarded with cyber attack after cyber attack, I explained to my grandparents the concept of end-to-end encryption and how phishing was not the same as a peaceful afternoon on a lake. ”

Make it Fun!

Students make the mistake of thinking their college essays have to be serious and hyper-professional. While you don’t want to be throwing around slang and want to present yourself in a positive light, you shouldn’t feel like you’re not allowed to have fun with your essay. Let your personality shine and crack a few jokes.

You can, and should, also get creative with your essay. A great way to do this in a computer science essay is to incorporate lines of code or write the essay like you are writing out code. 

Now we will go over a real “ Why Computer Science? ” essay a student submitted and explore what the essay did well, and where there is room for improvement.

Please note: Looking at examples of real essays students have submitted to colleges can be very beneficial to get inspiration for your essays. You should never copy or plagiarize from these examples when writing your own essays. Colleges can tell when an essay isn’t genuine and will not view students favorably if they plagiarized.

I held my breath and hit RUN. Yes! A plump white cat jumped out and began to catch the falling pizzas. Although my Fat Cat project seems simple now, it was the beginning of an enthusiastic passion for computer science. Four years and thousands of hours of programming later, that passion has grown into an intense desire to explore how computer science can serve society. Every day, surrounded by technology that can recognize my face and recommend scarily-specific ads, I’m reminded of Uncle Ben’s advice to a young Spiderman: “with great power comes great responsibility”. Likewise, the need to ensure digital equality has skyrocketed with AI’s far-reaching presence in society; and I believe that digital fairness starts with equality in education.

The unique use of threads at the College of Computing perfectly matches my interests in AI and its potential use in education; the path of combined threads on Intelligence and People gives me the rare opportunity to delve deep into both areas. I’m particularly intrigued by the rich sets of both knowledge-based and data-driven intelligence courses, as I believe AI should not only show correlation of events, but also provide insight for why they occur.

In my four years as an enthusiastic online English tutor, I’ve worked hard to help students overcome both financial and technological obstacles in hopes of bringing quality education to people from diverse backgrounds. For this reason, I’m extremely excited by the many courses in the People thread that focus on education and human-centered technology. I’d love to explore how to integrate AI technology into the teaching process to make education more available, affordable, and effective for people everywhere. And with the innumerable opportunities that Georgia Tech has to offer, I know that I will be able to go further here than anywhere else.

What the Essay Did Well 

This essay perfectly accomplishes the two key parts of a “ Why Computer Science? ” essay: answering “ Why This Major? ” and “ Why This College? ”. Not to mention, we get a lot of insight into this student and what they care about beyond computer science, and a fun hook at the beginning.

Starting with the “ Why This Major? ” aspect of the response, this essay demonstrates what got the student into computer science, why they are passionate about the subject, and what their goals are. They show us their introduction to the world of CS with an engaging hook: “I held my breath and hit RUN. Yes! A plump white cat jumped out and began to catch the falling pizzas. ” We then see this is a core passion because they spent “ Four years and thousands of hours ,” coding.

The student shows us why they care about AI with the sentence, “ Every day, surrounded by technology that can recognize my face and recommend scarily-specific ads ,” which makes the topic personal by demonstrating their fear at AI’s capabilities. But, rather than let panic overwhelm them, the student calls upon Spiderman and tells us their goal of establishing digital equality through education. This provides a great basis for the rest of the essay, as it thoroughly explains the students motivations and goals, and demonstrates their appreciation for interdisciplinary topics.

Then, the essay shifts into answering “ Why This College? ”, which it does very well by honing in on a unique facet of Georgia Tech’s College of Computing: threads. This is a great example of how to provide depth to the school resources you mention. The student describes the two threads and not only why the combination is important to them, but how their previous experiences (i.e. online English tutor) correlate to the values of the thread: “ For this reason, I’m extremely excited by the many courses in the People thread that focus on education and human-centered technology. ”

What Could Be Improved

This essay does a good job covering the basics of the prompt, but it could be elevated with more nuance and detail. The biggest thing missing from this essay is a strong core to tie everything together. What do we mean by that? We want to see a common theme, anecdote, or motivation that is weaved throughout the entire essay to connect everything. Take the Spiderman quote for example. If this was expanded, it could have been the perfect core for this essay.

Underlying this student’s interest in AI is a passion for social justice, so they could have used the quote about power and responsibility to talk about existing injustices with AI and how once they have the power to create AI they will act responsibly and help affected communities. They are clearly passionate about equality of education, but there is a disconnect between education and AI that comes from a lack of detail. To strengthen the core of the essay, this student needs to include real-world examples of how AI is fostering inequities in education. This takes their essay from theoretical to practical.

Whether you’re a seasoned writer or a novice trying your hand at college application essays, the review and editing process is crucial. A fresh set of eyes can provide valuable insights into the clarity, coherence, and impact of your writing. Our free Peer Essay Review tool offers a unique platform to get your essay reviewed by another student. Peer reviews can often uncover gaps, provide new insights or enhance the clarity of your essay, making your arguments more compelling. The best part? You can return the favor by reviewing other students’ essays, which is a great way to hone your own writing and critical thinking skills.

For a more professional touch, consider getting your essay reviewed by a college admissions expert . CollegeVine advisors have years of experience helping students refine their writing and successfully apply to top-tier schools. They can provide specific advice on how to showcase your strengths, address any weaknesses, and generally present yourself in the best possible light.

Should You Pursue a Career in Computer Science?

That depends on what you want to do for work, but if you’re interested in technology and you want to work with computers or technical systems and solutions, then this could be the perfect field for you.

There are many good reasons to think about studying computer science, but three of the most compelling reasons to specialize in this area include:

  • Demand for computer science professionals continues to rise and is projected to grow steadily over the next decade. 
  • Computer science professionals play a critical role wherever they work, developing complex solutions that help organizations overcome a variety of difficult challenges.
  • Jobs in computer science tend to pay excellent salaries.

To help give you a little more context on why you should take the opportunity to study computer science so seriously, let’s look at each of these in a bit more detail.

Demand for Computer Science Professionals is Projected to Continue Growing

The BLS reports that the employment of computer scientists will rise considerably over the next decade.

In fact, according to the BLS’s latest projections, demand for 3 of the best roles in the industry is set to explode between 2021 and 2031:

  • Computer and Information Research Scientists - 21% growth
  • Software Developers, Quality Assurance Analysts, and Testers - 25% growth
  • Computer Systems Analysts - 9% growth

Knowing that employment rates are going to rise by so much over the next decade, you can be confident that you’ll graduate from a Bachelor’s Degree program in Computer Science into a healthy job market looking to employ people with your particular skill set.

This is a great way to help increase the chances that your degree will make a measurable, positive impact on your career by helping you to secure stable employment in a growing, lucrative industry.

Computer Scientists Are Critical to Organizational Success

Because computer scientists are responsible for so many important tasks at modern organizations, they play a critical role in ensuring the health of nearly every business.

No matter which area of computer science you choose to specialize in, you can be nearly certain that the work you do will be important and useful to whatever organization ends up employing you.

According to a recent survey by Peldon Rose , employees report that feeling appreciated is the most important factor in determining their happiness at work, and playing a central, valued role as a computer science professional could be a great way to improve the chances that you’ll truly enjoy what you do each day throughout your career.

Playing a critical role won’t just make you feel good though, and as we’re about to see, it might also help ensure that you’re well paid.

Computer Scientists Have Excellent Earnings Potential 

Skilled computer scientists can earn considerable incomes, especially after finding themselves employed in some of the industry’s best jobs.

The BLS reports great rates of compensation for some of the more popular jobs in computer science, including:

  • Computer Programmers /  2021 Median Pay: $93,000
  • Computer Systems Analysts /  2021 Median Pay: $99,270

And while this is just a very short list of the many potential positions you could pursue after completing your B.S. in Computer Science, the good news is that other jobs in this field also tend to pay relatively high salaries.

Income isn’t the only thing that matters to people, but if you do feel it’s important to focus your efforts on building a career in a field with good earning potential, then you might be hard-pressed to find a better niche than computer science. 

H ow to Launch Your Career in Computer Science 

It’s certainly possible to break into the field without a degree, but you’re likely to have an easier time landing your first job, and landing a good job, if you’ve got the education credentials to prove that you know what you’re doing.

Why? Because computer science positions are so important to business success that hiring managers looking to fill open positions are extremely likely to prefer candidates with a degree on their resume.

Getting your degree in computer science proves that you’ve dedicated the time and effort required to develop your knowledge, skills, and abilities in the field, increasing the chances that you’ll be able to deliver real value to an organization.

Completing a B.S. in Computer Science certainly won’t guarantee that you’re able to get a job in the field, but it should allow you to pursue good jobs in the industry with the full confidence that you’re prepared to make a meaningful contribution wherever you choose to apply.

Century of Science: Theme

  • The future of computing

Everywhere and invisible

You are likely reading this on a computer. You are also likely taking that fact for granted. That’s even though the device in front of you would have astounded computer scientists just a few decades ago, and seemed like sheer magic much before that. It contains billions of tiny computing elements, running millions of lines of software instructions, collectively written by countless people across the globe. The result: You click or tap or type or speak, and the result seamlessly appears on the screen.

One mill of the analytical engine

Computers once filled rooms. Now they’re everywhere and invisible, embedded in watches, car engines, cameras, televisions and toys. They manage electrical grids, analyze scientific data and predict the weather. The modern world would be impossible without them, and our dependence on them for health, prosperity and entertainment will only increase.

Scientists hope to make computers faster yet, to make programs more intelligent and to deploy technology in an ethical manner. But before looking at where we go from here, let’s review where we’ve come from.

In 1833, the English mathematician Charles Babbage conceived a programmable machine that presaged today’s computing architecture, featuring a “store” for holding numbers, a “mill” for operating on them, an instruction reader and a printer. This Analytical Engine also had logical functions like branching (if X, then Y). Babbage constructed only a piece of the machine, but based on its description, his acquaintance Ada Lovelace saw that the numbers it might manipulate could represent anything, even music, making it much more general-purpose than a calculator. “A new, a vast, and a powerful language is developed for the future use of analysis,” she wrote. She became an expert in the proposed machine’s operation and is often called the first programmer.

Colossus machine

In 1936, the English mathematician Alan Turing introduced the idea of a computer that could rewrite its own instructions , making it endlessly programmable. His mathematical abstraction could, using a small vocabulary of operations, mimic a machine of any complexity, earning it the name “universal Turing machine.”

The first reliable electronic digital computer, Colossus, was completed in 1943, to help England decipher wartime codes. It used vacuum tubes — devices for controlling the flow of electrons — instead of moving mechanical parts like the Analytical Engine’s cogwheels. This made Colossus fast, but engineers had to manually rewire it every time they wanted to perform a new task. Perhaps inspired by Turing’s concept of a more easily reprogrammable computer, the team that created the United States’ first electronic digital computer , ENIAC, drafted a new architecture for its successor, the EDVAC. The mathematician John von Neumann, who penned the EDVAC’s design in 1945, described a system that could store programs in its memory alongside data and alter the programs, a setup now called the von Neumann architecture. Nearly every computer today follows that paradigm.


In 1947, researchers at Bell Telephone Laboratories invented the transistor , a piece of circuitry in which the application of voltage (electrical pressure) or current controls the flow of electrons between two points. It came to replace the slower and less efficient vacuum tubes. In 1958 and 1959, researchers at Texas Instruments and Fairchild Semiconductor independently invented integrated circuits, in which transistors and their supporting circuitry were fabricated on a chip in one process.

For a long time, only experts could program computers. Then in 1957, IBM released FORTRAN, a programming language that was much easier to understand. It’s still in use today. In 1981 the company unveiled the IBM PC and Microsoft released its operating system called MS-DOS, together expanding the reach of computers into homes and offices. Apple further personalized computing with the operating systems for its Lisa, in 1982, and Macintosh, in 1984. Both systems popularized graphical user interfaces, or GUIs, offering users a mouse cursor instead of a command line.

Arpanet map

Meanwhile, researchers had been doing work that would end up connecting our newfangled hardware and software. In 1948, the mathematician Claude Shannon published “ A Mathematical Theory of Communication ,” a paper that popularized the word bit (for binary digit) and laid the foundation for information theory . His ideas have shaped computation and in particular the sharing of data over wires and through the air. In 1969, the U.S. Advanced Research Projects Agency created a computer network called ARPANET, which later merged with other networks to form the internet. In 1990, researchers at CERN — a European laboratory near Geneva, Switzerland — developed rules for transmitting data that would become the foundation of the World Wide Web.

Better hardware, better software and better communication have now connected most of the people on the planet. But how much better can the processors get? How smart can algorithms become? And what kinds of benefits and dangers should we expect to see as technology advances? Stuart Russell, a computer scientist at University of California, Berkeley and coauthor of a popular textbook on artificial intelligence, sees great potential for computers in “expanding artistic creativity, accelerating science, serving as diligent personal assistants, driving cars and — I hope — not killing us.” — Matthew Hutson

Jobs and Mac

Chasing speed

Computers, for the most part, speak the language of bits. They store information — whether it’s music, an application or a password — in strings of 1s and 0s. They also process information in a binary fashion, flipping transistors between an “on” and “off” state. The more transistors in a computer, the faster it can process bits, making possible everything from more realistic video games to safer air traffic control.

Combining transistors forms one of the building blocks of a circuit, called a logic gate. An AND logic gate, for example, is on if both inputs are on, while an OR is on if at least one input is on. Together, logic gates compose a complex traffic pattern of electrons, the physical manifestation of computation. A computer chip can contain millions of such logic gates.

So the more logic gates, and by extension the more transistors, the more powerful the computer. In 1965, Gordon Moore, a cofounder of Fairchild Semiconductor and later of Intel, published a paper on the future of chips titled “Cramming More Components onto Integrated Circuits.” He graphed the number of components (mostly transistors) on five integrated circuits (chips) that had been built from 1959 to 1965, and extended the line. Transistors per chip had doubled every year, and he expected the trend to continue.

Original Moore graph

In a 1975 talk, Moore identified three factors behind this exponential growth: smaller transistors, bigger chips and “device and circuit cleverness,” such as less wasted space. He expected the doubling to occur every two years. It did, and continued doing so for decades. That trend is now called Moore’s law.

Moore’s law is not a physical law, like Newton’s law of universal gravitation. It was meant as an observation about economics. There will always be incentives to make computers faster and cheaper — but at some point, physics interferes. Chip development can’t keep up with Moore’s law forever, as it becomes more difficult to make transistors tinier. According to what’s jokingly called Moore’s second law, the cost of chip fabrication plants, or “fabs,” doubles every few years. The semiconductor company TSMC has considered building a plant that would cost $25 billion.

Today, Moore’s law no longer holds; doubling is happening at a slower rate. We continue to squeeze more transistors onto chips with each generation, but the generations come less frequently. Researchers are looking into several ways forward: better transistors, more specialized chips, new chip concepts and software hacks.  

Computer performance from 1985 through 2015

Modern Moore graph

Until about 2005, the ability to squeeze more transistors onto each chip meant exponential improvements in computer performance (black and gray show an industry benchmark for computers with one or more “cores,” or processors). Likewise, clock frequency (green) — the number of cycles of operations performed per second — improved exponentially. Since this “Dennard-scaling era,” transistors have continued to shrink but that shrinking hasn’t yielded the same performance benefits.


Transistors can get smaller still. Conceptually, a transistor consists of three basic elements. A metal gate (different from the logic gates above) lays across the middle of a semiconductor, one side of which acts as an electron source, and the other side a drain. Current passes from source to drain, and then on down the road, when the gate has a certain voltage. Many transistors are of a design called FinFET, because the channel from source to drain sticks up like a fin or a row of fins. The gate is like a larger, perpendicular wall that the fins pass through. It touches each fin on both sides and the top.

But, according to Sanjay Natarajan, who leads transistor design at Intel, “we’ve squeezed, we believe, everything you can squeeze out of that architecture.” In the next few years, chip manufacturers will start producing gate-all-around transistors, in which the channel resembles vertically stacked wires or ribbons penetrating the gate. These transistors will be faster and require less energy and space.

Transistors revisited

Finfet and gate all around transistor drawings

New transistor designs, a shift from the common FinFET (left) to gate-all-around transistors (right), for example, can make transistors that are smaller, faster and require less energy.

As these components have shrunk, the terminology to describe their size has gotten more confusing. You sometimes hear about chips being “14 nanometers” or “10 nanometers” in size; top-of-the-line chips in 2021 are “5 nanometers.” These numbers do not refer to the width or any other dimension of a transistor. They used to refer to the size of particular transistor features, but for several years now they have been nothing more than marketing terms.

Chip design

Even if transistors were to stop shrinking, computers would still have a lot of runway to improve, through Moore’s “device and circuit cleverness.”

A large hindrance to speeding up chips is the amount of heat they produce while moving electrons around. Too much and they’ll melt. For years, Moore’s law was accompanied by Dennard scaling, named after electrical engineer Robert Dennard, who said that as transistors shrank, they would also become faster and more energy efficient. That was true until around 2005, when they became so thin that they leaked too much current, heating up the chip. Since then, computer clock speed — the number of cycles of operations performed per second — hasn’t increased beyond a few gigahertz.

Core memory weavers and Navajo women made the Apollo missions possible

The stories of the women who assembled integrated circuits and wove core memory for the Apollo missions remain largely unknown.

Computers are limited in how much power they can draw and in how much heat they can disperse. Since the mid-2000s, according to Tom Conte, a computer scientist at Georgia Tech in Atlanta who co-leads the IEEE Rebooting Computing Initiative, “power savings has been the name of the game.” So engineers have turned to making chips perform several operations simultaneously, or splitting a chip into multiple parallel “cores,” to eke more operations from the same clock speed. But programming for parallel circuits is tricky.

Another speed bump is that electrons often have to travel long distances between logic gates or between chips — which also produces a lot of heat. One solution to the delays and heat production of data transmission is to move transistors closer together. Some nascent efforts have looked at stacking them vertically. More near-term, others are stacking whole chips vertically. Another solution is to replace electrical wiring with fiber optics, as light transmits information faster and more efficiently than electrical current does.

TrueNorth chip

Increasingly, computers rely on specialized chips or regions of a chip, called accelerators. Arranging transistors differently can put them to better use for specific applications. A cell phone, for instance, may have different circuitry designed for processing graphics, sound, wireless transmission and GPS signals.

“Sanjay [Natarajan] leads the parts of Intel that deliver transistors and transistor technologies,” says Richard Uhlig, managing director of Intel Labs. “We figure out what to do with the transistors,” he says of his team. One type of accelerator they’re developing is for what’s called fully homomorphic encryption, in which a computer processes data while it’s still encrypted — useful for, say, drawing conclusions about a set of medical records without revealing personal information. The project, funded by DARPA, could speed homomorphic encryption by hundreds of times.

More than 200 start-ups are developing accelerators for artificial intelligence , finding faster ways to perform the calculations necessary for software to learn from data.

Some accelerators aim to mimic, in hardware, the brain’s wiring. These “neuromorphic” chips typically embody at least one of three properties. First, memory elements may sit very close to computing elements, or the same elements may perform both functions, the way neurons both store and process information. One type of element that can perform this feat is the memristor . Second, the chips may process information using “spikes.” Like neurons, the elements sit around waiting for something to happen, then send a signal, or spike, when their activation crosses a threshold. Third, the chips may be analog instead of digital, eliminating the need for encoding continuous electrical properties such as voltage into discrete 1s and 0s.

These neuromorphic properties can make processing certain types of information orders of magnitude faster and more energy efficient. The computations are often less precise than in standard chips, but fuzzy logic is acceptable for, say, pattern matching or finding approximate solutions quickly. Uhlig says Intel has used its neuromorphic chip Loihi in tests to process odors, control robots and optimize railway schedules so that many trains can share limited tracks.

Cerebras chip

Some types of accelerators might one day use quantum computing , which capitalizes on two features of the subatomic realm. The first is superposition , in which particles can exist not just in one state or another, but in some combination of states until the state is explicitly measured. So a quantum system represents information not as bits but as qubits , which can preserve the possibility of being either 0 or 1 when measured. The second is entanglement , the interdependence between distant quantum elements. Together, these features mean that a system of qubits can represent and evaluate exponentially more possibilities than there are qubits — all combinations of 1s and 0s simultaneously.

Qubits can take many forms, but one of the most popular is as current in superconducting wires. These wires must be kept at a fraction of a degree above absolute zero, around –273° Celsius, to prevent hot, jiggling atoms from interfering with the qubits’ delicate superpositions and entanglement. Quantum computers also need many physical qubits to make up one “logical,” or effective, qubit, with the redundancy acting as error correction .

Quantum computers have several potential applications: machine learning, optimization (like train scheduling) and simulating real-world quantum mechanics, as in chemistry. But they will not likely become general-purpose computers. It’s not clear how you’d use one to, say, run a word processor.

New chip concepts

There remain new ways to dramatically speed up not just specialized accelerators but also general-purpose chips. Conte points to two paradigms. The first is superconduction. Below about 4 kelvins, around –269° C, many metals lose almost all electrical resistance, so they won’t convert current into heat. A superconducting circuit might be able to operate at hundreds of gigahertz instead of just a few, using much less electricity. The hard part lies not in keeping the circuits refrigerated (at least in big data centers), but in working with the exotic materials required to build them. 

The second paradigm is reversible computing. In 1961, the physicist Rolf Landauer merged information theory and thermodynamics , the physics of heat. He noted that when a logic gate takes in two bits and outputs one, it destroys a bit, expelling it as entropy, or randomness, in the form of heat. When billions of transistors operate at billions of cycles per second, the wasted heat adds up. Michael Frank, a computer scientist at Sandia National Laboratories in Albuquerque who works on reversible computing, wrote in 2017: “A conventional computer is, essentially, an expensive electric heater that happens to perform a small amount of computation as a side effect.”

But in reversible computing, logic gates have as many outputs as inputs. This means that if you ran the logic gate in reverse, you could use, say, three out-bits to obtain the three in-bits. Some researchers have conceived of reversible logic gates and circuits that could not only save those extra out-bits but also recycle them for other calculations. The physicist Richard Feynman had concluded that, aside from energy loss during data transmission, there’s no theoretical limit to computing efficiency.

Combine reversible and superconducting computing, Conte says, and “you get a double whammy.” Efficient computing allows you to run more operations on the same chip without worrying about power use or heat generation. Conte says that, eventually, one or both of these methods “probably will be the backbone of a lot of computing.”

Software hacks

Researchers continue to work on a cornucopia of new technologies for transistors, other computing elements, chip designs and hardware paradigms: photonics, spintronics , biomolecules, carbon nanotubes . But much more can still be eked out of current elements and architectures merely by optimizing code.

In a 2020 paper in Science , for instance, researchers studied the simple problem of multiplying two matrices, grids of numbers used in mathematics and machine learning. The calculation ran more than 60,000 times faster when the team picked an efficient programming language and optimized the code for the underlying hardware, compared with a standard piece of code in the Python language, which is considered user-friendly and easy to learn.

Computing gains through hardware and algorithm improvement

Algorithm improvement chart

Hardware isn’t the only way computing speeds up. Advances in the algorithms — the computational procedures for achieving a result — can lend a big boost to performance. The graph above shows the relative number of problems that can be solved in a fixed amount of time for one type of algorithm. The black line shows gains over time from hardware and algorithm advances; the purple line shows gains from hardware improvements alone.

Neil Thompson, a research scientist at MIT who coauthored the Science paper, recently coauthored a paper looking at historical improvements in algorithms , abstract procedures for tasks like sorting data. “For a substantial minority of algorithms,” he says, “their progress has been as fast or faster than Moore’s law.”

People have predicted the end of Moore’s law for decades. Even Moore has predicted its end several times. Progress may have slowed, at least for the time being, but human innovation, accelerated by economic incentives, has kept technology moving at a fast clip. — Matthew Hutson

Chasing intelligence

From the early days of computer science, researchers have aimed to replicate human thought. Alan Turing opened a 1950 paper titled “ Computing Machinery and Intelligence ” with: “I propose to consider the question, ‘Can machines think?’” He proceeded to outline a test, which he called “the imitation game” ( now called the Turing test ), in which a human communicating with a computer and another human via written questions had to judge which was which. If the judge failed, the computer could presumably think.

Man with wires

The term “artificial intelligence” was coined in a 1955 proposal for a summer institute at Dartmouth College. “An attempt will be made,” the proposal goes, “to find how to make machines use language, form abstractions and concepts, solve kinds of problems now reserved for humans, and improve themselves.” The organizers expected that over two months, the 10 summit attendees would make a “significant advance.”

More than six decades and untold person-hours later, it’s unclear whether the advances live up to what was in mind at that summer summit. Artificial intelligence surrounds us, in ways invisible (filtering spam), headline-worthy (beating us at chess, driving cars) and in between (letting us chat with our smartphones). But these are all narrow forms of AI, performing one or two tasks well. What Turing and others had in mind is called artificial general intelligence, or AGI. Depending on your definition, it’s a system that can do most of what humans do.

We may never achieve AGI, but the path has led, and will lead, to lots of useful innovations along the way. “I think we’ve made a lot of progress,” says Doina Precup, a computer scientist at McGill University in Montreal and head of AI company DeepMind’s Montreal research team. “But one of the things that, to me, is still missing right now is more of an understanding of the principles that are fundamental in intelligence.”

AI has made great headway in the last decade, much of it due to machine learning. Previously, computers relied more heavily on symbolic AI, which uses algorithms, or sets of instructions, that make decisions according to manually specified rules. Machine-learning programs, on the other hand, process data to find patterns on their own. One form uses artificial neural networks, software with layers of simple computing elements that together mimic certain principles of biological brains. Neural networks with several, or many more, layers are currently popular and make up a type of machine learning called deep learning.


Deep-learning systems can now play games like chess and Go better than the best human. They can probably identify dog breeds from photos better than you can. They can translate text from one language to another. They can control robots and compose music and predict how proteins will fold.

But they also lack much of what falls under the umbrella term of common sense. They don’t understand fundamental things about how the world works, physically or socially. Slightly changing images in a way that you or I might not notice, for example, can dramatically affect what a computer sees. Researchers found that placing a few innocuous stickers on a stop sign can lead software to interpret the sign as a speed limit sign, an obvious problem for self-driving cars .

Artificial intelligence challenges what it means to be creative

Computer programs can mimic famous artworks, but struggle with originality and lack self-awareness.

Types of learning

How can AI improve? Computer scientists are leveraging multiple forms of machine learning, whether the learning is “deep” or not. One common form is called supervised learning, in which machine-learning systems, or models, are trained by being fed labeled data such as images of dogs and their breed names. But that requires lots of human effort to label them. Another approach is unsupervised or self-supervised learning, in which computers learn without relying on outside labels, the way you or I predict what a chair will look like from different angles as we walk around it.

Models that process billions of words of text, predicting the next word one at a time and changing slightly when they’re wrong, rely on unsupervised learning. They can then generate new strings of text. In 2020, the research lab OpenAI released a trained language model called GPT-3 that’s perhaps the most complex neural network ever. Based on prompts, it can write humanlike news articles, short stories and poems. It can answer trivia questions, write computer code and translate language — all without being specifically trained to do any of these things. It’s further down the path toward AGI than many researchers thought was currently possible. And language models will get bigger and better from here.

Neural network

Another type of machine learning is reinforcement learning , in which a model interacts with an environment, exploring sequences of actions to achieve a goal. Reinforcement learning has allowed AI to become expert at board games like Go and video games like StarCraft II . A recent paper by researchers at DeepMind, including Precup, argues in the title that “ Reward Is Enough .” By merely having a training algorithm reinforce a model’s successful or semi-successful behavior, models will incrementally build up all the components of intelligence needed to succeed at the given task and many others.

For example, according to the paper, a robot rewarded for maximizing kitchen cleanliness would eventually learn “perception (to differentiate clean and dirty utensils), knowledge (to understand utensils), motor control (to manipulate utensils), memory (to recall locations of utensils), language (to predict future mess from dialogue) and social intelligence (to encourage young children to make less mess).” Whether trial and error would lead to such skills within the life span of the solar system — and what kinds of goals, environment and model would be required — is to be determined.

Another type of learning involves Bayesian statistics, a way of estimating what conditions are likely given current observations. Bayesian statistics is helping machines identify causal relations, an essential skill for advanced intelligence.


To learn efficiently, machines (and people) need to generalize, to draw abstract principles from experiences. “A huge part of intelligence,” says Melanie Mitchell, a computer scientist at the Santa Fe Institute in New Mexico, “is being able to take one’s knowledge and apply it in different situations.” Much of her work involves analogies, in a most rudimentary form: finding similarities between strings of letters. In 2019, AI researcher François Chollet of Google created a kind of IQ test for machines called the Abstraction and Reasoning Corpus, or ARC, in which computers must complete visual patterns according to principles demonstrated in example patterns. The puzzles are easy for humans but so far challenging for machines. Eventually, AI might understand grander abstractions like love and democracy.

Machine IQ test

Blocky tests

In a kind of IQ test for machines, computers are challenged to complete a visual patterning task based on examples provided. In each of these three tasks, computers are given “training examples” (both the problem, left, and the answer, right) and then have to determine the answer for “test examples.” The puzzles are typically much easier for humans than for machines.

Much of our abstract thought, ironically, may be grounded in our physical experiences. We use conceptual metaphors like important = big, and argument = opposing forces. AGI that can do most of what humans can do may require embodiment, such as operating within a physical robot. Researchers have combined language learning and robotics by creating virtual worlds where virtual robots simultaneously learn to follow instructions and to navigate within a house. GPT-3 is evidence that disembodied language may not be enough. In one demo , it wrote: “It takes two rainbows to jump from Hawaii to seventeen.”

“I’ve played around a lot with it,” Mitchell says. “It does incredible things. But it can also make some incredibly dumb mistakes.”

AGI might also require other aspects of our animal nature, like emotions , especially if humans expect to interact with machines in natural ways. Emotions are not mere irrational reactions. We’ve evolved them to guide our drives and behaviors. According to Ilya Sutskever, a cofounder and the chief scientist at OpenAI, they “give us this extra oomph of wisdom.” Even if AI doesn’t have the same conscious feelings we do, it may have code that approximates fear or anger. Already, reinforcement learning includes an exploratory element akin to curiosity .

Stop sign stickers

One function of curiosity is to help learn causality, by encouraging exploration and experimentation, Precup says. However, current exploration methods in AI “are still very far from babies playing purposefully with objects,” she notes.

Humans aren’t blank slates. We’re born with certain predispositions to recognize faces, learn language and play with objects. Machine-learning systems also require the right kind of innate structure to learn certain things quickly. How much structure, and what kind, is a matter of intense debate in the field. Sutskever says building in how we think we think is “intellectually seductive,” and he leans toward blank slates. However, “we want the best blank slate.”

One general neural-network structure Sutskever likes is called the transformer, a method for paying greater attention to important relationships between elements of an input. It’s behind current language models like GPT-3, and has also been applied to analyzing images, audio and video. “It makes everything better,” he says.

Thinking about thinking

AI itself may help us discover new forms of AI. There’s a set of techniques called AutoML, in which algorithms help optimize neural-network architectures or other aspects of AI models. AI also helps chip architects design better integrated circuits. This year, Google researchers reported in Nature that reinforcement learning performed better than their in-house team at laying out some aspects of an accelerator chip they’d designed for AI.

Estimates of AGI’s proximity vary greatly, but most experts think it’s decades away. In a 2016 survey, 352 machine-learning researchers estimated the arrival of “high-level machine intelligence,” defined as “when unaided machines can accomplish every task better and more cheaply than human workers.” On average, they gave even odds of such a feat by around 2060.

But no one has a good basis for judging. “We don’t understand our own intelligence,” Mitchell says, as much of it is unconscious. “And therefore, we don’t know what’s going to be hard or easy for AI.” What seems hard can be easy and vice versa — a phenomenon known as Moravec’s paradox, after the roboticist Hans Moravec. In 1988, Moravec wrote, “it is comparatively easy to make computers exhibit adult-level performance in solving problems on intelligence tests or playing checkers, and difficult or impossible to give them the skills of a 1-year-old when it comes to perception and mobility.” Babies are secretly brilliant. In aiming for AGI, Precup says, “we are also understanding more about human intelligence, and about intelligence in general.”

The gap between organic and synthetic intelligence sometimes seems small because we anthropomorphize machines, spurred by computer science terms like intelligence , learning and vision . Aside from whether we even want humanlike machine intelligence — if they think just like us, won’t they essentially just be people, raising ethical and practical dilemmas? — such a thing may not be possible. Even if AI becomes broad, it may still have unique strengths and weaknesses.

Turing also differentiated between general intelligence and humanlike intelligence. In his 1950 paper on the imitation game, he wrote, “May not machines carry out something which ought to be described as thinking but which is very different from what a man does?” — Matthew Hutson

Ethical issues

In the 1942 short story “Runaround,” one of Isaac Asimov’s characters enumerated “the three fundamental Rules of Robotics — the three rules that are built most deeply into a robot’s positronic brain.” Robots avoided causing or allowing harm to humans, they obeyed orders and they protected themselves, as long as following one rule didn’t conflict with preceding decrees.

We might picture Asimov’s “positronic brains” making autonomous decisions about harm to humans, but that’s not actually how computers affect our well-being every day. Instead of humanoid robots killing people, we have algorithms curating news feeds. As computers further infiltrate our lives, we’ll need to think harder about what kinds of systems to build and how to deploy them, as well as meta-problems like how to decide — and who should decide — these things.

This is the realm of ethics, which may seem distant from the supposed objectivity of math, science and engineering. But deciding what questions to ask about the world and what tools to build has always depended on our ideals and scruples. Studying an abstruse topic like the innards of atoms , for instance, has clear bearing on both energy and weaponry. “There’s the fundamental fact that computer systems are not value neutral,” says Barbara Grosz, a computer scientist at Harvard University, “that when you design them, you bring some set of values into that design.”

One topic that has received a lot of attention from scientists and ethicists is fairness and bias . Algorithms increasingly inform or even dictate decisions about hiring, college admissions, loans and parole. Even if they discriminate less than people do, they can still treat certain groups unfairly, not by design but often because they are trained on biased data. They might predict a person’s future criminal behavior based on prior arrests, for instance, even though different groups are arrested at different rates for a given amount of crime.

Percent of population that would be targeted by predictive policing

Bar charts on Oakland drug use (side by side)

A predictive policing algorithm tested in Oakland, Calif., would target Black people at roughly twice the rate of white people (right) even though data from the same time period, 2011, show that drug use was roughly equivalent across racial groups (left).

And confusingly, there are multiple definitions of fairness, such as equal false-positive rates between groups or equal false-negative rates between groups. A researcher at one conference listed 21 definitions . And the definitions often conflict. In one paper , researchers showed that in most cases it’s mathematically impossible to satisfy three common definitions simultaneously.

Another concern is privacy and surveillance , given that computers can now gather and sort information on their use in a way previously unimaginable . Data on our online behavior can help predict aspects of our private lives, like sexuality. Facial recognition can also follow us around the real world, helping police or authoritarian governments. And the emerging field of neurotechnology is already testing ways to connect the brain directly to computers. Related to privacy is security — hackers can access data that’s locked away, or interfere with pacemakers and autonomous vehicles.

Computers can also enable deception. AI can generate content that looks real. Language models might write masterpieces or be used to fill the internet with fake news and recruiting material for extremist groups. Generative adversarial networks, a type of deep learning that can generate realistic content, can assist artists or create deepfakes , images or videos showing people doing things they never did.

Putin Obama example

On social media, we also need to worry about polarization in people’s social, political and other views. Generally, recommendation algorithms optimize engagement (and platform profit through advertising), not civil discourse. Algorithms can also manipulate us in other ways. Robo-advisers — chatbots for dispensing financial advice or providing customer support — might learn to know what we really need, or to push our buttons and upsell us on extraneous products.

Multiple countries are developing autonomous weapons that have the potential to reduce civilian casualties as well as escalate conflict faster than their minders can react. Putting guns or missiles in the hands of robots raises the sci-fi specter of Terminators attempting to eliminate humankind. They might even think they’re helping us because eliminating humankind also eliminates human cancer (an example of having no common sense). More near-term, automated systems let loose in the real world have already caused flash crashes in the stock market and Amazon book prices reaching into the millions . If AIs are charged with making life-and-death decisions, they then face the famous trolley problem, deciding whom or what to sacrifice when not everyone can win. Here we’re entering Asimov territory.

That’s a lot to worry about. Russell, of UC Berkeley, suggests where our priorities should lie: “Lethal autonomous weapons are an urgent issue, because people may have already died, and the way things are going, it’s only a matter of time before there’s a mass attack,” he says. “Bias and social media addiction and polarization are both arguably instances of failure of value alignment between algorithms and society, so they are giving us early warnings of how things can easily go wrong.” He adds, “I don’t think trolley problems are urgent at all.”


There are also social, political and legal questions about how to manage technology in society. Who should be held accountable when an AI system causes harm? (For instance, “confused” self-driving cars have killed people .) How can we ensure more equal access to the tools of AI and their benefits, and make sure they don’t harm some groups much more than others? How will automating jobs upend the labor market? Can we manage the environmental impact of data centers, which use a lot of electricity? (Bitcoin mining is responsible for as many tons of carbon dioxide emissions as a small country.) Should we preferentially employ explainable algorithms — rather than the black boxes of many neural networks — for greater trust and debuggability, even if it makes the algorithms poorer at prediction?

What can be done

Michael Kearns, a computer scientist at the University of Pennsylvania and coauthor of The Ethical Algorithm , puts the problems on a spectrum of manageability. At one end is what’s called differential privacy, the ability to add noise to a dataset of, say, medical records so that it can be shared usefully with researchers without revealing much about the individual records. We can now make mathematical guarantees about exactly how private individuals’ data should remain.

Somewhere in the middle of the spectrum is fairness in machine learning. Researchers have developed methods to increase fairness by removing or altering biased training data, or to maximize certain types of equality — in loans, for instance — while minimizing reduction in profit. Still, some types of fairness will forever be in mutual conflict, and math can’t tell us which ones we want.

At the far end is explainability. As opposed to fairness, which can be analyzed mathematically in many ways, the quality of an explanation is hard to describe in mathematical terms. “I feel like I haven’t seen a single good definition yet,” Kearns says. “You could say, ‘Here’s an algorithm that will take a trained neural network and try to explain why it rejected you for a loan,’ but [the explanation] doesn’t feel principled.”

Explanation methods include generating a simpler, interpretable model that approximates the original, or highlighting regions of an image a network found salient, but these are just gestures toward how the cryptic software computes. Even worse, systems can provide intentionally deceptive explanations , to make unfair models look fair to auditors. Ultimately, if the audience doesn’t understand it, it’s not a good explanation, and measuring its success — however you define success — requires user studies.  

Something like Asimov’s three laws won’t save us from robots that hurt us while trying to help us; stepping on your phone when you tell it to hurry up and get you a drink is a likely example. And even if the list were extended to a million laws, the letter of a law is not identical to its spirit. One possible solution is what’s called inverse reinforcement learning, or IRL. In reinforcement learning, a model learns behaviors to achieve a given goal. In IRL, it infers someone’s goal by observing their behavior. We can’t always articulate our values — the goals we ultimately care about — but AI might figure them out by watching us. If we have coherent goals, that is.

“Perhaps the most obvious preference is that we prefer to be alive,” says Russell, who has pioneered IRL. “So an AI agent using IRL can avoid courses of action that cause us to be dead. In case this sounds too trivial, remember that not a single one of the prototype self-driving cars knows that we prefer to be alive. The self-driving car may have rules that in most cases prohibit actions that cause death, but in some unusual circumstance — such as filling a garage with carbon monoxide — they might watch the person collapse and die and have no notion that anything was wrong.”

Digital lives

Facebook metaverse

In 2021, Facebook unveiled its vision for a metaverse, a virtual world where people would work and play. “As so many have made clear, this is what technology wants,” says MIT sociologist and clinical psychologist Sherry Turkle about the metaverse. “For me, it would be wiser to ask first, not what technology wants, but what do people want? What do people need to be safer? Less lonely? More connected to each other in communities? More supported in their efforts to live healthier and more fulfilled lives?”

Engineer, heal thyself

In the 1950 short story “The Evitable Conflict,” Asimov articulated what became a “zeroth law,” which would supersede the others: “A robot may not harm humanity, or, by inaction, allow humanity to come to harm.” It should go without saying that the rule should apply with “roboticist” in place of “robot.” For sure, many computer scientists avoid harming humanity, but many also don’t actively engage with the social implications of their work, effectively allowing humanity to come to harm, says Margaret Mitchell, a computer scientist who co-led Google’s Ethical AI team and now consults with organizations on tech ethics. (She is no relation to computer scientist Melanie Mitchell.)

One hurdle, according to Grosz, is that they’re not properly trained in ethics. But she hopes to change that. Grosz and the philosopher Alison Simmons began a program at Harvard called Embedded EthiCS, in which teaching assistants with training in philosophy are embedded in computer science courses and teach lessons on privacy or discrimination or fake news. The program has spread to MIT, Stanford and the University of Toronto.

“We try to get students to think about values and value trade-offs,” Grosz says. Two things have struck her. The first is the difficulty students have with problems that lack right answers and require arguing for particular choices. The second is, despite their frustration, “how much students care about this set of issues,” Grosz says.

Another way to educate technologists about their influence is to widen collaborations. According to Mitchell, “computer science needs to move from holding math up as the be-all and end-all, to holding up both math and social science, and psychology as well.” Researchers should bring in experts in these topics, she says. Going the other way, Kearns says, they should also share their own technical expertise with regulators, lawyers and policy makers. Otherwise, policies will be so vague as to be useless. Without specific definitions of privacy or fairness written into law, companies can choose whatever’s most convenient or profitable.

When evaluating how a tool will affect a community, the best experts are often community members themselves. Grosz advocates consulting with diverse populations. Diversity helps in both user studies and technology teams. “If you don’t have people in the room who think differently from you,” Grosz says, “the differences are just not in front of you. If somebody says not every patient has a smartphone, boom, you start thinking differently about what you’re designing.”

According to Margaret Mitchell, “the most pressing problem is the diversity and inclusion of who’s at the table from the start. All the other issues fall out from there.” — Matthew Hutson

How Computers Affect Our Lives: Essay Introduction

History of computers, positive effects of computer on human life, computers replacing man, negative computer influences, conflict with religious beliefs, conclusion: how computer influences our life, works cited.

Computers are a common phenomenon in the lives of people in today’s world. Computers are very vital especially to those people who run businesses, industries and other organizations. Today, almost everything that people engage in makes use of a computer. Take for instance, the transport sector: vehicles, trains, airplanes, and even traffic lights on our roads are controlled by computers.

In hospitals, most of the equipments use or are run by computers. Look at space exploration; it was all made possible with the advent of computer technology. In the job sector, many of the jobs require knowledge in computers because they mostly involve the use of computers.

In short, these machines have become so important and embedded in the lives of humans, they have hugely impacted on the whole society to the extent that it will be very hard to survive now, without them. This article discusses the influence of computers on the everyday life of human beings.

One can guess what will exactly happen if the world had no computers. Many of the cures found with help of computer technology would not have been developed without computer technology, meaning that many people would have died from diseases that are now curable. In the entertainment industry, many of the movies and even songs will not be in use without computers because most of the graphics used and the animations we see are only possible with the help of a computer (Saimo 1).

In the field of medicine, pharmacies, will find it hard in determining the type of medication to give to the many patients. Computers have also played a role in the development of democracy in the world. Today votes are counted using computers and this has greatly reduced incidences of vote rigging and consequently reduced conflicts that would otherwise arise from the same.

And as we have already seen, no one would have known anything about space because space explorations become possible only with the help of computer technology. However, the use of computers has generated public discourses whereby people have emerged with different views, some supporting their use and others criticizing them (Saimo 1).

To better understand how computers influence the lives of people, we will have to start from the history, from their invention to the present day. Early computers did not involve complex technologies as the ones that are used today; neither did they employ the use of monitors or chips that are common today.

The early computers were not that small as those used today and they were commonly used to help in working out complex calculations in mathematics that proved tedious to be done manually. This is why the first machine was called by some as a calculator and others as a computer because it was used for making calculations.

Blaise Pascal is credited with the first digital machine that could add and subtract. Many versions of calculators and computers borrowed from his ideas. And as time went by, many developed more needs, which lead to modifications to bring about new and more efficient computers (Edwards 4).

Computer influence in the life of man became widely felt during World War II where computers were used to calculate and track the movements and also strategize the way military attacks were done (Edwards 4). It is therefore clear, that computers and its influence on man have a long history.

Its invention involved hard work dedication and determination, and in the end it paid off. The world was and is still being changed by computers. Man has been able to see into the future and plan ahead because of computers. Life today has been made easier with the help of computers, although some people may disagree with this, but am sure many will agree with me.

Those who disagree say that computers have taken away the role of man, which is not wrong at all, but we must also acknowledge the fact what was seen as impossible initially, become possible because of computers (Turkle 22).

As we mentioned in the introduction, computers are useful in the running of the affairs of many companies today. Companies nowadays use a lot of data that can only be securely stored with the help of computers. This data is then used in operations that are computer run. Without computers companies will find it difficult store thousands of records that are made on a daily basis.

Take for instance, what will happen to a customer checking his or her balance, or one who just want to have information on transactions made. In such a case, it will take long to go through all the transactions to get a particular one.

The invention of computers made this easier; bank employees today give customers their balances, transaction information, and other services just by tapping the computer keyboard. This would not be possible without computers (Saimo 1).

In personal life

Today individuals can store all information be it personal or that of a business nature in a computer. It is even made better by being able to make frequent updates and modifications to the information. This same information can be easily retrieved whenever it is needed by sending it via email or by printing it.

All this have been made possible with the use of computers. Life is easier and enjoyable, individuals now can comfortably entertain themselves at home by watching TV with their families or they can work from the comfort of their home thanks to computer technology.

Computers feature in the everyday life of people. Today one can use a computer even without being aware of it: people use their credit cards when buying items from stores; this has become a common practice that few know that the transaction is processed through computer technology.

It is the computer which process customer information that is fed to it through the credit card, it detects the transaction, and it then pays the bill by subtracting the amount from the credit card. Getting cash has also been made easier and faster, an individual simply walks to an ATM machine to withdraw any amount of cash he requires. ATM machines operate using computer technology (Saimo 1).

I mentioned the use of credit cards as one of the practical benefits of using computers. Today, individual do not need to physically visit shopping stores to buy items. All one needs is to be connected on the internet and by using a computer one can pay for items using the credit card.

These can then be delivered at the door step. The era where people used to queue in crowded stores to buy items, or wasting time in line waiting to buy tickets is over. Today, travelers can buy tickets and make travel arrangements via the internet at any time thanks to the advent of computer technology (Saimo 1).

In communication

Through the computer, man now has the most effective means of communication. The internet has made the world a global village. Today people carry with them phones, which are basically small computers, others carry laptops, all these have made the internet most effective and affordable medium of communication for people to contact their friends, their families, contact business people, from anywhere in the world.

Businesses are using computer technology to keep records and track their accounts and the flow of money (Lee 1). In the area of entertainment, computers have not been left behind either.

Action and science fiction movies use computers to incorporated visual effects that make them look real. Computer games, a common entertainer especially to teenagers, have been made more entertaining with the use of advanced computer technology (Frisicaro et.al 1).

In Education

The education sector has also been greatly influenced by computer technology. Much of the school work is done with the aid of a computer. If students are given assignments all they have to do is search for the solution on the internet using Google. The assignments can then be neatly presented thanks to computer software that is made specifically for such purposes.

Today most high schools have made it mandatory for students to type out their work before presenting it for marking. This is made possible through computers. Teachers have also found computer technology very useful as they can use it to track student performance. They use computers to give out instructions.

Computers have also made online learning possible. Today teachers and students do not need to be physically present in class in order to be taught. Online teaching has allowed students to attend class from any place at any time without any inconveniences (Computers 1).

In the medical sector

Another very crucial sector in the life of man that computers has greatly influenced and continues to influence is the health sector. It was already mentioned in the introduction that hospitals and pharmacies employ the use of computers in serving people.

Computers are used in pharmacies to help pharmacists determine what type and amount of medication patients should get. Patient data and their health progress are recorded using computers in many hospitals. The issue of equipment status and placement in hospitals is recorded and tracked down using computers.

Research done by scientists, doctors, and many other people in the search to find cures for many diseases and medical complications is facilitated through computer technology. Many of the diseases that were known to be dangerous such as malaria are now treatable thanks to computer interventions (Parkin 615).

Many of the opponents of computer technology have argued against the use of computers basing their arguments on the fact that computers are replacing man when carrying out the basic activities that are naturally human in nature.

However, it should be noted that there are situations that call for extraordinary interventions. In many industries, machines have replaced human labor. Use of machines is usually very cheap when compared to human labor.

In addition machines give consistent results in terms of quality. There are other instances where the skills needed to perform a certain task are too high for an ordinary person to do. This is usually experienced in cases of surgery where man’s intervention alone is not sufficient. However, machines that are computer operated have made complex surgeries successful.

There are also cases where the tasks that are to be performed may be too dangerous for a normal human being. Such situations have been experienced during disasters such as people being trapped underground during mining. It is usually dangerous to use people in such situations, and even where people are used, the rescue is usually delayed.

Robotic machines that are computer operated have always helped in such situations and people have been saved. It is not also possible to send people in space duration space explorations, but computer machines such as robots have been effectively used to make exploration outside our world (Gupta 1).

Despite all these good things that computers have done to humans, their opponents also have some vital points that should not just be ignored. There are many things that computers do leaving many people wondering whether they are really helping the society, or they are just being used to deprive man his God given ability to function according to societal ethics.

Take for instance in the workplace and even at home; computers have permeated in every activity done by an individual thereby compromising personal privacy. Computers have been used to expose people to unauthorized access to personal information. There is some personal information, which if exposed can impact negatively to someone’s life.

Today the world does not care about ethics to the extent that it is very difficulty for one to clearly differentiate between what is and is not authentic or trustful. Computers have taken up every aspect of human life, from house chores in the home to practices carried out in the social spheres.

This has seen people lose their human element to machines. Industries and organizations have replaced human labor for the cheap and more effective machine labor. This means that people have lost jobs thanks to the advances made in the computer technology. Children using computers grow up with difficulties of differentiating between reality and fiction (Subrahmanyam et.al 139).

People depend on computers to do tasks. Students generate solutions to assignments using computers; teachers on the other hand use computers to mark assignments. Doctors in hospitals depend on machines to make patient diagnoses, to perform surgeries and to determine type of medications (Daley 56).

In the entertainment industry, computer technology has been used to modify sound to make people think that person singing is indeed great, but the truth of the matter is that it is simply the computer. This has taken away the really function of a musician in the music sector.

In the world of technology today, we live as a worried lot. The issue of hacking is very common and even statistics confirm that huge amounts of money are lost every year through hacking. Therefore, as much as people pride themselves that they are computer literate, they deeply worried that they may be the next victim to practices such as hacking (Bynum 1).

There is also the problem of trying to imitate God. It is believed that in 20 years time, man will come up with another form of life, a man made being. This will not only affect how man will be viewed in terms of his intelligence, but it will also break the long held view that God is the sole provider of life.

Computers have made it possible to create artificial intelligence where machines are given artificial intelligence so that they can behave and act like man. This when viewed from the religious point of view creates conflicts in human beliefs.

It has been long held that man was created in the image of God. Creating a machine in the image of money will distort the way people conceive of God. Using artificial methods to come up with new forms of life with man like intelligence will make man equate himself to God.

This carries the risk of changing the beliefs that mankind has held for millions of years. If this happens, the very computer technology will help by the use of mass media to distribute and convince people to change their beliefs and conceptions of God (Krasnogor 1).

We have seen that computer have and will continue to influence our lives. The advent of the computers has changed man as much as it has the world he lives in.

It is true that many of the things that seemed impossible have been made possible with computer technology. Medical technologies have led to discoveries in medicine, which have in turn saved many lives. Communication is now easy and fast. The world has been transformed into a virtual village.

Computers have made education accessible to all. In the entertainment sector, people are more satisfied. Crime surveillance is better and effective. However, we should be ware not to imitate God. As much as computers have positively influenced our lives, it is a live bomb that is waiting to explode.

We should tread carefully not to be overwhelmed by its sophistication (Computers 1). Many technologies have come with intensities that have seen them surpass their productivity levels thereby destroying themselves in the process. This seems like one such technology.

  • Essay on Computer


Long and Short Computer Essay

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers. 

In this essay, we will discuss the various components and types of computers and talk about their uses in various fields.

Long Computer Essay in English

A computer is an electronic tool that manipulates data or information. It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them. 

Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations. 

Common Components of Computers

All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory (RAM), motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices.

 There are five main hardware components: 

Input Devices: 

These are devices that are used to enter data/information in the central processing unit. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc.

Output Devices: 

These are devices that provide the processed data/information into human-readable form. Example- monitor, printer, speaker, projector etc.

Control Unit: 

The control unit handles the various components of the computer; it reads and interprets (decodes) the instructions for the program, transforming them into control signals that activate other computer parts.

Arithmetic Logic Unit: 

It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc., and square roots.

Central Processing Unit: 

The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application.

Software refers to computer parts, such as programs, data, protocols, etc., that do not have a material form. In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions.

It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer.

Computer hardware and software require each other, and neither of them can be realistically used on their own. There are four main components of a general-purpose computer: the arithmetic logic unit (ALU), the control unit, the memory, and the I/O (collectively called input and output) devices.

Uses of Computer

Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions. They have taken sectors and companies to a whole new level.


Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other.


Computers in the government sector are used to perform various functions and improve their services. In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers. In addition to this, computers play a key role in the country's defence system.

Health and Medicine- 

They are used to preserve information, records, live patient monitoring, X-rays, and more from patients. Computers assist in setting up laboratory tools, monitoring heart rate and blood pressure, etc. Besides, computers allow physicians to easily exchange patient data with other medical specialists.


They help people get different educational materials (such as images, videos, e-books, etc.) in one place. Also, computers are best suited for online classes, online tutoring, online exams, and task and project creation. Also, they can be used to maintain and track student performance and other data.


Most countries use online banking systems so that customers can access their data directly. People can verify the balance of their account, transfer cash, and pay online bills, including credit cards. Besides, banks use computers to execute transactions and store client information, transaction records, etc.

Short Computer Essay in English

A computer's a programmable device that accepts raw data(input) and processes it as output with a group of instructions (a program) to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.

Types of Computer

Computers are of different types based on different criteria. Based on their size, computers are of five types:

Micro Computers- 

It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants (PDAs), tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc.

Mini Computers- 

Minicomputers are also referred to as "Midrange Computers." They are multi-user computers designed to simultaneously support multiple users. Therefore, they are generally used by small companies and firms. 

Mainframe Computers- 

It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders.

Super Computer- 

Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.


It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer.

Benefits of Computers:

It increases productivity.

It helps in connecting to the internet.

It helps in organizing data and information.

It allows storing large amounts of data.

Fun Facts About Computers

The first electric computer that was invented weighed around 27 tons or even more than that and took up to 1800 square feet.

There are about 5000 new viruses that are released every month.

The original name of Windows was Interface Manager.

It is surely known that the life of humans would not have been so easy if computers were not a part of human life. This is also supported by a lot of pieces of evidence where we can even see in daily life how the computer is not just present in an organization but is also available right in the pockets of everyone. Thus, the computer has surely made it easy while also spoiling a lot of people's lives. 


FAQs on Essay on Computer

1. What are the disadvantages of computers?

While the computer has surely made life easier, it also has a lot of disadvantages. The disadvantages of the computers can be provided as follows:

People spend too much time sitting and doing nothing but watching the content on computers.

People staring at computers for a long time also tend to strain their eyes, and as a result, they need spectacles to understand what is being written in front of them.

Attention span is decreasing with an increase in the use of computers. 

With computers being AI-powered, it is now easier for people to do all the tasks on a computer and not work on it themselves. This has made a lot of people lazy.

2. What is the process of working on a computer?

A computer is an electronic machine and it needs information to be added in as raw data to function well. It has a flow that determines the accessing of data. The following steps take place before the results are obtained:

Information is taken in by the computer in the form of raw data. This process is also called the input.

Then the information that is not needed will be stored while the information that is needed is passed onto the next step. The storing of data is called memory.

Then the information that is required is crushed or it is split and this process is called processing.

The last step is where the results are obtained. This process is called getting the output.

The Importance of Computer Science in Healthcare

Today’s healthcare systems rely heavily on technology and programming. Without the widespread integration of computer science in healthcare, medicine and related disciplines would be close to a century behind the current standards.

Table of Contents

Health Informatics as the Meeting Point of Two Disciplines

Computer science and healthcare may seem like very different fields at first glance. Computer science deals with the complexities of computational systems, while healthcare involves providing medical care to communities. However, a new field called health informatics seeks to merge these two disparate areas by exploring how computer science can be used to improve healthcare.

Its goal is to improve the efficiency and quality of healthcare by creating systems that can store, process, analyze, and communicate information related to healthcare. This includes electronic health records, medical decision-support systems, and remote monitoring systems.

Today, health informatics has evolved and expanded to include new technologies such as artificial intelligence, machine learning, data analytics, and blockchain. These technologies are enabling doctors to better diagnose diseases, make decisions more quickly, reduce costs, and improve safety.

The Role of Computer Science in Healthcare Practice

Healthcare practice is everything related to clinical operations, which mainly involves doctor-patient interactions, diagnostics, treatments, and follow-up care.

Now, however, most of the medical records are kept within compact hard drives or in the cloud, saving space and time needed to extract them. Electronic medical records (EMR) allow physicians to access patient records, their medical history and diagnostic test results, within seconds at a click of a computer mouse.

4. Diagnostic Tests

Some diagnostic tests are only possible with the use of automated computer systems, including polymerase chain reaction (PCR) tests, computerized tomography, MRI, and PET scans.

5. Medical Devices

Ever been in a hospital and heard devices beeping all around you? Yes, all of those devices use programming to function.

In fact, modern healthcare systems are heavily dependent on automated medical devices that measure and monitor vital signs in real-time. These include pulse oximeters, blood pressure monitors, ECG machines, and ventilators.

6. Public Health

Finally, computer science plays an immense role in public health. Computer modeling and analysis are used to understand the spread of infectious diseases, as well as research on epidemiology. The use of predictive algorithms can also help identify populations at risk for certain diseases.

The Role of Computer Science in Healthcare Research

Using algorithms and complex programming, researchers can analyze data from a variety of sources, such as genomic data and medical records. These data can be used to identify drug targets, create personalized therapies, and even diagnose diseases.

Computers: essay on the importance of computer in the modern society.

essay on role of computer in modern science


Read this comprehensive essay on the Importance of Computer in the Modern Society !

As the world progresses on in this never ending chase for a time and wealth, it is undeniable that science has made astounding developments.


Image Courtesy : upload.wikimedia.org/wikipedia/commons/thumb/f/fb//05.jpg

As the 21st century looms ahead, it is clear to see that it has advancements that humanity may never have dreamed of and one of these shining developments is the well-recognized computer. Having the Latin meaning of ‘computing’ or ‘reckoning’ the computer is an invention that was called the ‘MAN OF THE YEAR’ in a survey carried out by an international magazine.

The computer system is not a simple machine. It is like a very modern and highly complex calculator. It can do all the functions at a speedy rate and also helps us to search and progress in our homes and businesses. A computer can therefore be called a calculator with a twist for not only does it perform fast calculations, but it also has other special characteristics. The computer has thoroughly changed the way we witness things, with its special auto correcting tools, which work with all languages, all logic and all subjects.

There was a time when computers were only heard of as a luxury. However today they are an unavoidable part of success and development. No longer are they owned only through theft and by the filthy rich, in fact computers are and will in the coming days and months be used to accomplish the brilliant goals of success and unparalleled development. For example, in India, the accurate knowledge and use of computers will bring change in a big and astonishing way. It will lead to the demolition of illiteracy, and lead to optimism, efficiency, productivity and high quality.

Even now in our day to day lives, computers have been allotted an integral role to play. They can be seen being used not only at the office or at home, but in all kinds of sectors and businesses. They are used at airports, restaurants, railway stations, banks etc. slowly and gradually, as computers are penetrating through the modern society, people are getting more and more optimistic about the promises its invention made. They are also used in the government sectors, businesses and industry, and through witnessing the rapid progress of the computer; mankind slowly sees the lights it has brought along.

One of the best things about the computer is the fact that it can help us to save so much of manual power, cost, and time. By the use of a computer, tasks can be done automatically and that will lead to saving the countless hours that may otherwise have been spent on doing the job manually.

Computers also ensure more accuracy. Examples of such cases include ticket booking, payment of bills, insurance and shopping. Interestingly, automatic operations of vehicles, like trains also help to ensure further safety and reliability of the journey. Computers can be used to observe and predict traffic patterns which would be a grand benefit to all and would save the hassle of getting stuck for hours in the roadblocks and traffics.

Computers can also drastically change the way agricultural tasks and businesses are carried out all over the world. With regard to agriculture, computers are being used to find out the best possible kinds of soil, plants and to check which match of these would result in the perfect crops. Use of computers thus in this sector along with the use of better agricultural practices and products in several countries, like India, could help the agricultural industry reach soaring heights, directly assuring the welfare of the economy.

It is also wonderful to see that the invention of this unbelievable machine has brought a ray of hope in the darkness of the sick citizens’ world. Computers are very capable of bringing along a medical revolution. Where in health sectors computers are being used for research regarding blood groups, medical histories, etc. and helping to improve medicine in a big way. The knowledge that computers are providing in this field may lead to better use and purchase of medicinal drugs and ensure better health. This also leads to a better diagnosing pattern and makes health care faster and more efficiently.

Although computers are bringing the evolution of technology and changing the way lives are lived, it cannot be denied that there are areas where the impacts of the computer system are not fully recognized yet. For instance if we take the education sector, the literacy rates have not been improved by computers the way other sectors have seemed to have gotten better over night.

The fact remains that 64% of our population remains to date illiterate, and it will be a revolutionary act if computers were made the full use of and worked with to spread educational awareness, in all areas, especially the underprivileged sector. They can be used to plan out lessons, and lessons can be taught on the computers too, the benefit of the prospect lying in the fact that computers excel at lots of different things altogether, which means they can be used to teach not only limited subjects but be used to spread education with reference to all kinds, including text, numbers and graphics.

Perhaps one may think the horrendous thought that computers may take the teacher’s place in the classroom, but we must look at the prospect with the brighter side. No longer will the teacher remain a person who only fits data into a pupil’s mind; and once again become that one supreme authority who inculcates both philosophical and spiritual education amongst his or her students, rising in esteem and role play.

The advantage of computers can also be seen in the fact that they might just be able to improve administration through the world. By providing daily accurate information to the administration departments, computers may change the way decisions are taken across the globe.Keeping all the above mentioned things in mind, we must accept that if used the right way, computers are a gift of science to mankind.

Computers and Society: Modern Perspectives

713 Computers in education and learning

As we have already hinted, computers and the internet have made profound changes in how we learn. We begin this topic by reviewing influential visions and early prototypes suggesting how technology could revolutionize education. Early on, computers were used by educators to deliver online tutorials about subject material, administer drill-and-practice exercises on rote skills, act as supportive environ­ments for creatively exploring ideas through programming in English-like languages, and function as inexpensive, ubiquitous, and dynamic audio-visual resources. We shall then discuss other newer methods for using digital technologies to transform how students approach subject matter and how classrooms are organized. By using interactive simulation games, students learn by taking actions with respect to certain scenarios. Presentation aids such as PowerPoint and Prezi have replaced blackboards to present and elucidate concepts. Smart classrooms allow instructors and students access to technology that facilitates learning; inverted classrooms allow more effective use of class­room time by enabling students to prepare for lectures in advance and focus on working together with their teachers in class. Intelligent tutors are artificial intelligence (AI) programs that actively support student learning, diagnose student difficulties with the material, and then adapt tutoring strategies based on these findings. Next, we shall review how online learning has opened up new opportunities for adult and continuing education, whereby students can learn in their own time and at their own pace. The challenge online learning technology developers now face is to provide discussion forums, real-time chat capabilities, and methods for instructor feedback so that advantages of face-to-face interaction are not lost in web-based learning. Particularly exciting is the growth of worldwide learning communities via Massive Open Online Courses (MOOCs), an area of current expansion and creativity. While technology is now seen as instrumental in learning, there are still debates on the extent to which it should be used and how it should be used in education. A particularly prevalent dilemma is in middle and secondary schools. The issue is whether or not and how to encourage or disallow the use of mobile phones and other devices in classrooms.

Essay on The Role of Computers in Modern Life

The Role of Computers in Modern Life

The Role of Computers in Modern Life:

The twentieth century has witnessed a great advance in science and technology, and its applied form. The latest in this development is computer technology, which has come like a worldwide technical revolution. A computer is essentially a processing machine that can perform several important functions in a very short time. The functions are repetitive calculations, storage of information, decision making, providing information to the programmer on the basis of the information fed into the machine, control over certain other devices through signals, and helping in diagnosing diseases accurately.

During the last two decades, computer technology has shown remarkable development. Computers of various sizes and shapes have come up. The functions they perform now belong to different fields, ranging from space research to the diagnosis of diseases and industrial technology. They are now being used extensively in manufacturing and processing industries, power distribution system, airline, and railway reservation systems.

Computers are of tremendous help in offices too. Long and complicated information can be stored in computers and summoned at will. Besides, the data fed into the computers can be mixed and reorganized according to need. The old filing system for preserving information is becoming redundant. In departments such as income tax, where large documentation is necessary computers are providing very helpful indeed.

In the field of medicine, computers are used for diagnosing illness, monitoring patients, curing ailments, surgery, etc. For example, a pacemaker is a little computer, which is fixed inside patients having heart problems. Similarly, computers can be used to control tiny remote cameras which can take pictures inside the body and help doctors make diagnoses. Also, medical students learning surgery can practice operations on computers through virtual reality.

In space research, satellites and space laboratories are being controlled from a distance of millions of miles. The position of a Satellite in space can be adjusted, its functioning controlled and its defective parts repaired from the space laboratories on the earth. Computer technology has thus started working like what people used to dream of doing with the help of magic.

In industry, computers are proving to be highly helpful and effective. In the publishing industry, computers are making it possible to change and adjust the size of letters, opt for different varieties of print, and what is more, print accurately. In the textile industry, computer-made designs not only save a lot of labor but can also pour out design after design through combination and permutation of the material fed into them. In industrial sciences, computer technology not only provides accuracy but also speed and efficiency. There is now hardly any industry in which computers are not used, or cannot be used.

Scientists and technologists in the whole of the world are busy further improving and expanding the scope of computers. In printing, computers are doing the job much more effectively and accurately than human hands used to do before. In arts, especially painting, caricature, and music, computers, are being employed more and more frequently. They are very useful in making animation films too. A time may soon come when computerized robot slaves may start working in our houses. Designs, of such computers, have already been made, only the cost of production needs to be reduced.

Computers have thus become the new favorites. Because of their accuracy and fast work, they are regarded as a miraculous inventions of science. It needs to be said, however, that computers, like all other machines, are human inventions. They do not have any independent thinking power. They can only act according to the information and skill put into them. And both of these- the information and the skill to manipulate the given information- are given by human beings. So computers like traditional machines can be good slaves but bad masters if we submit ourselves entirely to them.

These modern machines permeate our home, work, and even entertainment. It has changed the way many industries operate. For example, travelers no longer need guides, the booking process is mostly online, and people are ready to take the path less known.

We want our farmers to become modern and tap the potential of the internet to get weather updates, seed availability, and market prices.

But, these advancements have their flip side too. People tend to have health issues because of long sitting hours, constant staring at the screen, and ensuing lethargy. For youngsters, social media addiction and virtual highs seem to be a complete menace.

It is in our onus that we take the pluses of the computers alone. In the race for catching up with the latest technology that is changing in the blink of the eye, let us not forget our roots.
