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.

Workstations-

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.

Computers are basically the electronic devices that are used to store and manipulate information that is retrievable and can be stored for long-term use. These devices have been in use since the nineteenth century. The use of computers has escalated in the 21 st century due to advancements in technology and the civilization in the society.

People use computers for different reasons and they value its use because of the benefits the computer has. During the development of computers, there have been several advancements which include the reduction in size and the improvement of speed and efficiency. The earliest computers, supercomputers, were huge and very slow while current computers, laptops, are very small yet very fast and efficient. Computers has actually evolved and with the trend of technological advancements, more discoveries are yet to be made.

Uses of Computers:

Computers are found in almost all fields i.e., education, healthcare, business, homes among other fields. The uses of computers cut across all fields for the basic functions and then differences in function are specific to fields. Computers are used to enter information and store them.

Based on the shred knowledge on computers, it is evident that its use has diversified globally. The use has increased efficiency and it has improved almost all sectors of life ranging from the social, economic, cultural and political. The use of computers has its pros and cons. Computers are actually essential because they complement human abilities and they will go a long way in improving the way of life.

Computer is one such man made device without which the mankind cannot imagine their existence. In short, a computer is a device that processes and stores information entered as the input and displays the information as the required output as and when the user desires.

Very huge in size and limited in functionality, the earlier computer was as big as an entire room and they consumed more power. It was in the year 1837 when Charles Babbage despite his limited resources and finances came up with a programmed version of the computer. Later, his son Henry Babbage modified the computer into a simpler unit. Initially, the use of computer was limited. They were merely used for calculations and not for carrying out tasks.

There was an important role played by computer in The World War II. War planning required huge calculations and with the aid of a computer, the armies found it easy.

A Luxury or Necessity:

There was a time when people considered the computer as a luxury but today it is a necessity. People cannot imagine their life without a computer. Well, it isn’t just a calculating device anymore. Modern computer carries out almost every task that the human desires. A computer nowadays is designed to store information and perform innumerable tasks as and when the user wants.

The information entered by the user is transmitted to the computer in the form of a programming language which is again transmitted into human language and the result is displayed.

Well, with computer becoming the backbone of almost every industry running today, you can very well judge whether it is a luxury or a necessity. It hasn’t just simplified tasks and made them quicker but computer has given birth to many other amazing inventions.

It is literally impossible to list the uses of a computer because the list is exhaustive. Basically, a computer nowadays performs innumerable tasks and it is required in every field. Thus, computer has been made a compulsory subject in primary schools almost everywhere. It has become an indispensable need for mankind and we cannot go a day without a computer. Available in varied designs and sizes, the modern day computer has also been modified into a portable form called a laptop. You can carry it wherever you go.

Be it offices, shops, schools, homes, and almost every other place; people cannot imagine their life without a computer. It is one such invention that has made human life super easy.

Well, just like everything has its share of advantage and disadvantages the same goes for computer.

The increasing rate in cybercrime is the biggest disadvantage that comes with computer. But if apt preventive measures are taken then maybe we can remedy the situation. Owing to the advantages computer has to offer we can overlook the few disadvantages it has.

The fast moving life that people are living nowadays is only possible because of this wonderful invention. With the passage of time, there has been an unbelievable advancement in the field of computer and the world has been constantly changing since then.

Owing to the rapid pace with which the computer industry has progressed, it can be rightly said that the coming days will be brighter, smarter and technically more advanced because we are sure to come up with even better computer systems. The next generations are sure to live an advanced life because with computer becoming better there’s no looking back.

Electronic devices on a whole might be making us lazy but we cannot deny the fact that computer is not just any ordinary electronic device; it is a boon to the human race.

Computers have been around in various forms for the past two centuries. Over that relatively short period of time this machine, or tool, has transformed mankind equally as much as fire or the wheel. That being said sometimes we take this device for granted and do not appreciate all the different things it is giving us.

When you stop and think about all the places where you can find a computer you will realize that almost all human endeavors in the present have some form of computerized help. Without this help, people wouldn’t be able to do their jobs as efficiently as they do now so let’s take a deeper look at the development of this amazing tool.

People have made many different tools all through history that they used to help them calculate and keep track of their resources. The idea has been around for a couple of thousand years but the technology was not advanced enough for us to make anything that resembles our modern computers till the 20 th century.

The first computers were analog devices that were used for solving different problems, that is they could perform an operation based on a predetermined mechanism that was usually based on a mathematical equation. That type of computer did not have enough flexibility to be used for many tasks and it could not be reprogramed. The first digital computer was called Z3 and it was developed in 1941 after successive models were upgraded.

The age that saw the birth of the computer also saw many changes in technology and manufacturing that made computer parts available for mass use. Those developments led to the invention of personal computers that were much cheaper and easier to use and once the public got hold of them a revolution in their usage was sparked.

The Present:

The present is all about computers and almost every home in the world has a computer, or that’s what we believe. The estimate from 2015 states that over 2 billion computers are in use today. The number suggests that there are a lot of devices all over the world being used every single moment. You are probably reading this from a computer and if not, you are reading it from a device that owes its existence to the computer and electronics revolution mentioned in the segment above.

Some people have suggested that computers are having a bad influence on people because they are making us distant from each other and because people tend to spend most of their day sitting in front of the computer looking like they are doing nothing. The fact is this is not something the computer does but rather the people who use them. Like with most other things in life that give us enjoyment we sometimes tend to misuse them and cause harm to ourselves.

The fact is that the present looks like it does because of the time and resources computers have saved us and this is an undisputed fact. Without this technology, we couldn’t manage half the production process running today not to mention our daily tasks that have in some circumstances become completely dependent on this device.

The Future:

Computers are becoming more complex and at the same time simpler to use making them widely distributed with a tendency to take over the world. There are many plans for the future of computers and as time goes by, they are capable of finding solutions to complex and unimagined problems. They are used in almost all the industries from mining to hospitality management and everywhere they find a unique task, or several, that they can perform.

They have become so indispensable to our lives that some people are actually considering making them a part of their body and integrating the computer operations with the organism. This can sound a bit bizarre but people are actually making advancements in this field and cyborg devices are being implemented to help people with disabilities more often as time passes.

The potential the computer has to help us is immense and the limit is only our imagination and the resources we have at our disposal. This tool can be thought to perform endless tasks even the experts get surprised sometimes. The future looks like its full of stars but we have to keep in mind that through their use we speed up all our processes altering our existence in a sense we have to keep both eyes open for signs of potentially dangerous outcomes of some of the technological advancements we use.

A computer, in terms of definition, is such a device, which through the use of computer programming, executes the arithmetic and logical operations. Computers are used as control frameworks for a wide assortment of modern and shopper gadgets. This includes simple gadgets like microwaves and remote controls, plant gadgets, for example, modern robots and computer helped structure, and furthermore broadly useful gadgets like computers and cell phones.

History of Computers:

Charles Babbage, an English mechanical designer and polymath, began the idea of a programmable computer. Considered as the father of the computer, he conceptualized and concocted the primary mechanical computer in the mid-nineteenth century. In the wake of chipping away at his progressive distinction motor, intended to help in navigational figuring, in 1833 he understood that a considerably more broad structure, an Analytical Engine, was conceivable.

The contribution of projects and information was to be given to the machine by means of punched cards, a strategy being utilized as an opportunity to coordinate mechanical weavers as the Jacquard linger. For yield, the machine would have a printer, a bend plotter and a ringer. The machine would similarly be able to punch numbers onto cards to be examined in later. The Engine consolidated a number juggling rationale unit, control stream as contingent stretching and circles, and incorporated memory, making it the primary plan for a broadly useful computer that could be portrayed in present-day terms as Turing-finish.

Parts of a Computer:

The essential parts of a computer are the computer case, monitor, keyboard, mouse, and power cord. Each part assumes an important role in the functioning of a computer. The computer case is the metal and plastic box that contains the principal parts of the computer including the motherboard, the CPU and power supply. The monitor works with a video card, situated inside the computer case, to show pictures and content on the screen.

Most monitors have control catches that enable you to change your screen’s showcase settings, and a few screens likewise have built-in speakers. The keyboard is one of the primary approaches to speak with a keyboard. There is a wide range of sorts of keyboards, yet most are fundamentally the same and enables you to achieve a similar essential feature. The mouse is another imperative device for speaking with computers. Ordinarily known as a pointing gadget, it gives you a chance to point to objects on the screen, tap on them, and move them.

Advantages of Computers:

Computers have no doubt made human life quicker as a result of extraordinary speed, accuracy and capacity, with which human can spare anything and pursuit it out effectively when required. We can state that computer is an adaptable machine since it is entirely adaptable in carrying out different occupations. The ability to do many tasks together, or in computer terms what is referred to as multitasking is one of the real advantages of a computer. An individual can carry out different undertakings, numerous tasks, and figure numerical issues within a couple of moments.

Computers can perform trillion of directions for every second. Other than this, one of the fundamental points of interest of a computer is its staggering pace, which causes human to finish their assignment in a couple of moments or even seconds. Each one of the activities can be performed in a quick manner in view of its speed otherwise it requires a long investment to complete the assignment.

Moreover, the storage capacity of computers is another of its abilities which make computers so powerful. You can store gigantic information inside a small hard disk. Concentrated database of putting away data is the significantly preferred standpoint that can lessen cost as well. One of the other advantages of computers is the precision of its calculations which are very hard to achieve manually.

The Other Side:

With the advent of technology, the computers have seen the darker side as well. Of late, there have been many instances of misuse of computers as well. For instance, viruses and hacking are two tools which are used to attack computers and misuse them. The virus is a worm and hacking is basically an unapproved access over a computer for some illegal reason. Viruses are exchanged from email connection, seeing a tainted site ad, through removable gadget like USB and so forth. Once malware is moved in host computer it can destroy the record, overwrite the document, and misuse them and so on.

For example, a huge bit of web was affected including Twitter, Netflix, and CNN in October 2016 on the grounds that the biggest DDoS assault was propelled on specialist organization DYN utilizing IoT Botnet. Such instances have given rise to cybercrimes. Cybercrimes imply computer system may have been utilized with the end goal to carry out unlawful activities. Cyber stalking and Identity burglary are the focuses which go under online digital crimes.

For example, one may get the access of your bank account or your shopping account like Amazon account and the hacker can have the capacity to access the bank account details or the credit or debit cards which can then be misused by the hacker. Moreover, with the increasing use of computers, there has been a decrease in the requirement of manual force as a lot of work has been taken over by computers. This was initially a cause of the increase in the rate of unemployment as well.

Computers – A Boon or a Curse?

There is no doubt that our lives have been made much easier with the introduction of computers. How easy it uses an ATM machine to withdraw money. In fact, online examinations which have removed the bias the students had to go through at the hands of teachers have been possible only with the use of computers. There are so many benefits of computers that is simply not possible to term them as a curse to our society.

However, everything must be sued judiciously, or else it does not take time for a boon to end up being a curse. For instance, we must make our kids understand the ill effects of using computers and cell phones for hours and encourage them to better reading and playing habits for them to go through their development process properly. Similarly, we must be aware of the cybercrimes one is prone to and follow the advice of the government from time to time in order to keep ourselves safe and secure from the ill effects of computers.

The Enduring Fascination and Scientific Value of Dinosaurs

How it works

1 Introduction
2 The Scientific Significance of Dinosaurs
3 Educational Value and Public Engagement
4 Dinosaurs in Popular Culture
5 Ethical and Conservation Lessons
6 Conclusion

Introduction

Dinosaurs have always fascinated us, haven’t they? From the time we first found their fossils to the latest movies with amazing CGI, these old giants have a special place in our hearts and minds. But they’re not just cool to look at. Studying dinosaurs helps us learn a lot about life on Earth, from evolution to climate change and even how the Earth itself has changed over millions of years. This essay will argue that keeping up with dinosaur research and teaching is super important.

It’s not just about science; it helps us understand our planet’s past and what might happen in the future.

The Scientific Significance of Dinosaurs

Why study dinosaurs? Well, first off, they teach us a ton about science. Dinosaurs were around for about 165 million years, during which a lot of stuff changed on Earth. By looking at their fossils, scientists can learn how life evolved. Take the Archaeopteryx, for example. Its discovery in the 19th century showed that birds and dinosaurs are related, which backed up Darwin’s theory of evolution. And then there’s the mass extinction that wiped out the dinosaurs. Studying that helps us understand today’s biodiversity crisis and how human activities might be affecting ecosystems.

Educational Value and Public Engagement

Dinosaurs aren’t just for scientists, though. They’re great for teaching people about science, too. Museums, TV shows, and school programs often use dinosaurs to get folks interested in bigger science ideas like paleontology and geology. Think about the American Museum of Natural History. Their dinosaur exhibits get millions of visitors every year. It’s a fun way to learn and can spark a lifelong love of science in kids and adults. Who knows? The next big scientist might get their start because they loved dinosaurs as a kid.

Dinosaurs in Popular Culture

We can’t ignore how big dinosaurs are in movies and TV. “Jurassic Park,” “Walking with Dinosaurs,” and tons of books and video games keep dinosaurs in the spotlight. This does two things. One, it keeps people interested in new dinosaur discoveries. Two, it helps fund science. The money made from dinosaur movies and games often goes to museums and research. So, popular culture helps keep the science going by getting people excited and providing financial support.

Ethical and Conservation Lessons

Dinosaurs also teach us about ethics and taking care of our planet. Their extinction, probably caused by an asteroid, shows us how fragile life is. It reminds us why it’s so important to protect endangered species. By looking at how dinosaurs went extinct, we can learn to better protect our ecosystems and react to environmental changes. This can push us to be more responsible with our planet and encourage conservation.

So, studying dinosaurs isn’t just for academics or for fun. It’s crucial for advancing science, educating the public, and helping us appreciate the complexity of life on Earth. Dinosaurs connect the past to the future, offering lessons that are still relevant today. As we keep learning about these ancient creatures, we better understand our world and how to handle future challenges. Therefore, ongoing research and education about dinosaurs are vital. They ensure that these prehistoric giants stay a key part of both our scientific studies and cultural stories.
