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-

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.
