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.

Science-

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.

Government-

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.

Education-

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.

Banking-

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.

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.

The use of computers does not limit 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 rate. 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 have turned out to be 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 cases were rising rapidly, we were locked in our houses and no sector was working except the medical sector. During these times when we understood the importance of computers in our life 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 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.

Essays About Computers: Top 5 Examples Plus Prompts

Computers are helpful technology that many of us use on a daily basis; if you are writing essays about computers, use our essay examples and prompts below.

We often recognize computers as the devices we use to browse the internet, communicate with others, and type down notes, but there is more to a computer than this. A complex set of processes, calculations, and operations performs everything we do on a computer. Without a doubt, computers make our lives easier and enhance our personal and working life.

5 Top Essay Examples

1. types of computers by brent dawson, 2. uses of computers in education by kristina barroso, 3. our dependency on computers by nora fox, 4. neural networks: is your brain like a computer by shamli prakash.

5. The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

1. The Many Uses of Computers

2. can computers take over society, 3. is computer science a worthwhile program to study, 4. pros and cons of computers, 5. can computers compete with the human brain.

“Calculations for things such as automotive design, weather forecasting, and aerospace use supercomputers. Embedded computers are used for functions in a larger product. They are located in things such as automobiles, consumer electronics and office machines. As we all know computers come in many shapes and sizes. They can be used for many different things and can be located anywhere. Technology has increased so much that the most unheard compact thing can be a computer.

Dawson stresses that computers can come in all shapes and sizes. There are different types of computers, such as personal computers, mobile computers, game consoles, and supercomputers, each with its own functions and specialties. He briefly touches on each type of computer and its uses. Technology has come a long way, as the most complex computers are everywhere, whether in laboratories, offices, or even our mobile phones or watches.

“Critics argue that spell check and other computer features that automatically correct errors in spelling and punctuation make students too lazy to learn and apply the rules themselves. These features, however, help point out where students went wrong and offer valuable learning opportunities that can help students enhance their understanding of appropriate spelling and punctuation.”

In her essay, Barroso discusses the advantages and disadvantages of incorporating computers into education. They allow schools to maximize online resources, foster student engagement, and make it easier for teachers and students to perform school-related tasks. However, they may make students lazy to check mistakes, thinking that the computers will automatically check them. Ultimately, the pros outweigh the cons.

“As far as I concerned, computer is a great invention and it is useful to human life. It should be impossible to live without computer as we get too much used of computers nowadays. However, we should use it wisely. We know the fact that the more we rely on computer, the more we will lose in our life. So, we should also find ways to make our dependence on computers less dangerous to us, so that we will not rely on computer completely.”

Fox discusses the state of society today where we rely far too much on computers. They help us greatly in our daily lives, but they have made us depend on technology for information rather than thinking for ourselves. And if something goes wrong, like the servers crash, the world is at a standstill. Computers are a net good for society, but we must avoid revolving our lives around technology.

“In data science terms, this phase is somewhat akin to ‘Model Training’ — the more things a child is exposed to the more the synapses associated with it get built. A good example is language — the more a child is exposed to linguistics in early years, the more evolved the area of her brain that is associated with languages would get. Ditto for other cognitive and non-cognitive abilities.”

Prakash discusses the different ways in which our brains operate as computers. An information processing system has five components: input, output, storage, processing, and program. The human brain does have all of these components, which are used to perform our daily functions. She looks into how human intelligence can be “trained,” like computers are developed.

5. The Human Brain vs. Supercomputers… Which One Wins? By John Staughton

“When the brain identifies a more efficient or effective way to compute and function, it can morph and alter its physical and neuronal structure, hence the term “plasticity“. Until we achieve true Artificial Intelligence (in which computers should theoretically be able to re-wire themselves), neuroplasticity will always keep the human brain at least one step ahead of “static” supercomputers.”

Staughton writes about how much more advanced computers have become in recent decades, with some of them being able to outsmart humans in tasks such as chess. However, he explains that our brains are very different from technology and are inherently superior to even the most powerful computers in terms of efficiency, adaptability, and many other factors. However, he keeps the door on computers, eventually developing beyond our capabilities in the future.

First Digital Computer

The first digital computer used plus 300 vacuum tubes and could perform mathematical calculations and Boolean logic. It was also called Atanasoff-Berry Computer (ABC Computer), after its two inventors John Vincent Atanasoff and Cliff Berry. They developed it from 1937-1942 at Iowa State College which is now Iowa State University.

First Electronic Computer (ENIAC)

ENIAC is an abbreviation of Electronic Numeric Integrator and Calculator, developed in 1943, at the University of Pennsylvania by J. Presper Eckert and John Mauchly. It was colossal, heavy and required 1800 square feet. It also used around 18,000 vacuum tubes and weighs approximately 50 tons. This was the first fully functional digital computer.

First Computer Company

The first computer company was founded in 1949 and it was named Electronics Control Company. It was founded by two persons who helped create the ENIAC – J. Presper Eckert and John Mauchly.

Modern computers have evolved through hundreds of years to reach the efficiency and shape that we see today. But, evolution is not over yet and will continue for centuries to come with the help of humans innovating to bring new technological advancements.

A computer is an electric device that is used to perform repetitive calculations at very high speed. The computer acts as a data processing device and also stores large amounts of data.

This data could be text, pictures, voice numbers, photographs and other types of information that are used by humans in their day-to-day operations. Life cannot be imagined without computers.

In fact, the new millennium is the era of computers and its associated techniques, commonly known as Information Technology (IT). Computers help the school children learn new techniques of study, graphic designs, games and other useful educational applications.

They help the college students in preparing reports. They help the office executives in accounts, software development, sale invoicing and manufacturing. They help the libraries in the efficient management of their operations. They run the factories and equipment. They control the satellites and nuclear weapons. They help the young and the old through Internet sites.

They are, in fact, indispensable as every operation of human life is incomplete and inefficient without them. As school-going students, we must learn computers Computers are available in various configurations.

For learning computer operations a computer with 166 MHz speed (Known as the CUP speed), an HDD of 1.2 MB storage capacity and RAM of 32 MB is needed.

A good computer, which would serve the purpose of the student, costs Rs. 30000 only. And this cost would come down in the years to come. Students should adopt computers in their educational teaming and for their mental development.

Computer software is a promising field and the students can build their careers in this field Moreover, intelligent programmers are also in great demand in the USA, the UK, Canada, Australia and New Zealand If the students work hard in the field of computers they would have good careers in the latter parts of their lives.

The word computer has been derived from the word “compute” which means “to count”. A computer is composed of “ hardware” and software”.Hardware means the physical parts of computer and software means the computer programmes that control the functioning of the hardware and directs its operation.

Computers were not invented over-night. It was an evolutionary process of centuries. In the beginning, computers were large in size. They were slow and their price was very high. With the passage of time, a great development has been done in the field of computer. Now, computers are smart, fast and cheap.

“The computer was born to solve problems that did not exist before.” — Bill Gates

Computers are being used for the exploration and extraction of all the possible benefits in the fields of medicine, education, business, banking, construction, communication, entertainment, research-work and science. New heights of delights are being felt and found in the exploration of new knowledge in every field of life. A computer has become a multipurpose device. It is playing a dominant role in our lives. Most of the things are being controlled and operated by computers.

The computer has made working very easy and effective in all the walks of life. Doctors and nurses use it to monitor patients and to assist in medical research. In business and industry, the computer helps us a lot to get information and to introduce new trends. It also helps us in the construction of bridges, roads and big buildings.

“It’s hardware that makes a machine fast. It’s software that makes a fast machine slow.” — Craig Bruce

The computer is rendering a great service in the banking system. It has revolutionized the telecommunication system. Telephone, mobile, radio, fax machines televisions are fully computerized now-a-days. A computer can quickly process the results of scientific experiments and solve extremely difficult problems easily. It is being used to guide rockets, satellites, spaceships and air flights. It has a very vast memory. The knowledge of all the books of a library can be stored on a computer. It can keep a record of thousands of files which are available in a moment. A number of softwares are available in the market and we can use them according to our needs to make our tasks easy and quick

“To every disadvantage, there is a corresponding advantage.” — W. Clement Stone

In spite of countless blessings of a computer, there is also a dark aspect of its usage. It has mechanized our life too much. We depend on computers too much and use our minds very less. The use of the internet is becoming very popular. Mostly youngsters waste their time in chatting and bluffing the others. There are also a number of immoral and obscene sites which are explored by the youngsters. It causes a very bad impact on their innocent minds. Moreover, computers are also creating a problem of unemployment in developing countries.

The modern age definitely is the age of information technology. Knowledge is advancing at a fantastic pace. Every new step unveils new vistas. Computers are playing a vital role in our social and economic life by turning the world into a global village. Now, thousands of books are available on one screen. The right use of computer can lead us to progress and prosperity. The computer and put future are interrelated. The world will be an orphan without a computer.

“The new electronic interdependence recreates

The world in the image of a global village.” (Marshall McLuhan).

Mechanical computing devices date from the 17 th century. Indeed Charles Babbage is credited with the invention of the computer. He named it the “Analytical Engine”. The first digital computer appeared in the USA in the 1940s. Since then generations have worked to reduce the size and increase the speed of the computer. Now it has proved to be the most amazing invention of the 20 th century. Computer scan and handles data with wonderful accuracy. The computer can read information and store this information for later use. Motherboard, Processor, RAM, Monitor, Key Board, Mouse, CD ROM and Floppy Drive are the main components of a computer.

Advantages and Uses of Computer

The benefits of a computer are many. The notable features of Computer are speed and accuracy. Life has become speedy and quick in this modern age. Thus, the importance of computer has been recognized in all fields of life. In industry, it keeps the record of goods, cost and output. It also provides a great deal of help in engineering. It designs buildings of all kinds, gives information about the best material to be used, suggests ideal measures for its safety and gives accurate expenditures of its construction. In medicine, it assists to perform tests, diagnoses diseases and prescribes medicine. In space, sea and earth explorations, it has performed wonders.

Disadvantages of Computer

Though the disadvantages of computers are equal to nought as compared with its uses, nevertheless, there are few physical and social problems associated with it. As far as physical harms of the computer are concerned, it causes stress and tension to the person who has to sit before it hours and hours together. Sometimes it weakens eyesight. It may cause a few social evils. On the internet, our youth can watch obscene movies and immoral pictures.

After analyzing computer from both the angles, it is easy to conclude that its uses are greater than its abuses. However, the evils of computers can be reduced to some extent by devising a code of ethics and awakening the sense of duty in our youth. Its physical evils can be controlled by certain exercises. To conclude, it may be said that the present age is the age of the computer. If we want to keep pace with the rest of the world, we will have to take adequate measures for the uplift of computer technology.

A Peek Inside the Brains of ‘Super-Agers’

New research explores why some octogenarians have exceptional memories.

Close up of a grey haired, wrinkled older woman’s eye.

By Dana G. Smith

When it comes to aging, we tend to assume that cognition gets worse as we get older. Our thoughts may slow down or become confused, or we may start to forget things, like the name of our high school English teacher or what we meant to buy at the grocery store.

But that’s not the case for everyone.

For a little over a decade, scientists have been studying a subset of people they call “super-agers.” These individuals are age 80 and up, but they have the memory ability of a person 20 to 30 years younger.

Most research on aging and memory focuses on the other side of the equation — people who develop dementia in their later years. But, “if we’re constantly talking about what’s going wrong in aging, it’s not capturing the full spectrum of what’s happening in the older adult population,” said Emily Rogalski, a professor of neurology at the University of Chicago, who published one of the first studies on super-agers in 2012.

A paper published Monday in the Journal of Neuroscience helps shed light on what’s so special about the brains of super-agers. The biggest takeaway, in combination with a companion study that came out last year on the same group of individuals, is that their brains have less atrophy than their peers’ do.

The research was conducted on 119 octogenarians from Spain: 64 super-agers and 55 older adults with normal memory abilities for their age. The participants completed multiple tests assessing their memory, motor and verbal skills; underwent brain scans and blood draws; and answered questions about their lifestyle and behaviors.

The scientists found that the super-agers had more volume in areas of the brain important for memory, most notably the hippocampus and entorhinal cortex. They also had better preserved connectivity between regions in the front of the brain that are involved in cognition. Both the super-agers and the control group showed minimal signs of Alzheimer’s disease in their brains.

“By having two groups that have low levels of Alzheimer’s markers, but striking cognitive differences and striking differences in their brain, then we’re really speaking to a resistance to age-related decline,” said Dr. Bryan Strange, a professor of clinical neuroscience at the Polytechnic University of Madrid, who led the studies.

These findings are backed up by Dr. Rogalski’s research , initially conducted when she was at Northwestern University, which showed that super-agers’ brains looked more like 50- or 60-year-olds’ brains than their 80-year-old peers. When followed over several years, the super-agers’ brains atrophied at a slower rate than average.

No precise numbers exist on how many super-agers there are among us, but Dr. Rogalski said they’re “relatively rare,” noting that “far less than 10 percent” of the people she sees end up meeting the criteria.

But when you meet a super-ager, you know it, Dr. Strange said. “They are really quite energetic people, you can see. Motivated, on the ball, elderly individuals.”

Experts don’t know how someone becomes a super-ager, though there were a few differences in health and lifestyle behaviors between the two groups in the Spanish study. Most notably, the super-agers had slightly better physical health, both in terms of blood pressure and glucose metabolism, and they performed better on a test of mobility . The super-agers didn’t report doing more exercise at their current age than the typical older adults, but they were more active in middle age. They also reported better mental health .

But overall, Dr. Strange said, there were a lot of similarities between the super-agers and the regular agers. “There are a lot of things that are not particularly striking about them,” he said. And, he added, “we see some surprising omissions, things that you would expect to be associated with super-agers that weren’t really there.” For example, there were no differences between the groups in terms of their diets, the amount of sleep they got, their professional backgrounds or their alcohol and tobacco use.

The behaviors of some of the Chicago super-agers were similarly a surprise. Some exercised regularly, but some never had; some stuck to a Mediterranean diet, others subsisted off TV dinners; and a few of them still smoked cigarettes. However, one consistency among the group was that they tended to have strong social relationships , Dr. Rogalski said.

“In an ideal world, you’d find out that, like, all the super-agers, you know, ate six tomatoes every day and that was the key,” said Tessa Harrison, an assistant project scientist at the University of California, Berkeley, who collaborated with Dr. Rogalski on the first Chicago super-ager study.

Instead, Dr. Harrison continued, super-agers probably have “some sort of lucky predisposition or some resistance mechanism in the brain that’s on the molecular level that we don’t understand yet,” possibly related to their genes.

While there isn’t a recipe for becoming a super-ager, scientists do know that, in general , eating healthily, staying physically active, getting enough sleep and maintaining social connections are important for healthy brain aging.

In photos: At least 83 dead as historic flooding hits southern Brazil

By Jintak Han | May 7, 2024

Record-breaking floods in Brazil’s southern Rio Grande do Sul state have killed at least 83 people over the past week, and another 111 were reported missing, local authorities said Monday.

Renan Mattos/Reuters

In the state capital, Porto Alegre, water levels of the Guaíba River peaked at 17.5 feet (5.33 meters) on Sunday — far exceeding the previous record of 15.6 feet (4.76 meters) observed in 1941, according to the prefectural government.

At least 291 people were injured, while damage from the rains forced more than 129,000 people from their homes. Approximately 20,000 took refuge in schools, gymnasiums and other temporary shelters.

The views expressed in IMF Working Papers are those of the author(s) and do not necessarily represent the views of the IMF, its Executive Board, or IMF management.

We show how the standard social welfare framework can be used to assess the performance of social safety nets (SSNs) in terms of targeting efficiency and budget effort. We apply this framework to the World Bank’s ASPIRE database and find that the variation in poverty alleviation achieved by SSNs in emerging markets and developing economies (EMDEs) is driven mainly by variation in budget effort. Increasing transfer spending is therefore key to strengthening SSNs in EMDEs. However, the inability of many EMDEs to finely target transfers to poor households means the required spending increases are prohibitive over the short term, especially in low-income countries. This emphasizes the importance of enhancing targeting efficiency and we discuss how the use of proxy-means testing can contribute to this emphasizing the importance of careful design to manage the horizontal inequity inherent in such an approach to targeting.
