Essay on Computer In English For Students & Teachers

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 apparatus that controls information or data. It can store, recover, and process data. We can type records, send messages, mess around, and peruse the Web utilizing a Computer. It can likewise be utilized to alter bookkeeping sheets, introductions, and even recordings, or make them.

Early Computers were imagined uniquely as gadgets for computing. Straightforward manual gadgets, for example, the math device have assisted people with doing computations since old times. A few mechanical gadgets were assembled from the get-go in the Industrial Revolution to mechanize long, monotonous errands, like directing examples for looms. In the mid twentieth century, more complex electrical machines performed specific simple estimations.

Common Components of Computers:


That large number of parts of a Computer that are substantial actual articles are covered under the term equipment. The equipment incorporates circuits, central processors, illustrations cards, sound cards, memory (RAM), motherboards, shows, power supplies, links, consoles, printers and “mice” input gadgets.

 There are five main hardware components:

  • Input Devices:

These are gadgets that are utilized to enter information/data in the focal handling unit. Model console, mouse, scanner, archive peruser, standardized tag peruser, optical person peruser, attractive peruser and so forth.

  • Output Devices:

These are gadgets that give the handled information/data into intelligible structure. Model screen, printer, speaker, projector and so forth.

  • Control Unit:

The control unit handles the different parts of the Computer; it peruses and deciphers (unravels) the directions for the program, changing them into control flags that initiate other Computer parts.

  • Arithmetic Logic Unit:

It is equipped for filling arithmetical and coherent roles. The arrangement of math tasks upheld by a particular ALU might be confined to expansion and deduction or may incorporate elements of duplication, division, geometries like sine, cosine, and so on, and square roots.

  • Central Processing Unit:

The ALU, control unit and registers and together called the CPU. It is in some cases called the Computer’s cerebrum, and its responsibility is to perform orders. We send directions to the CPU at whatever point we press a key, click the mouse, or begin an application.


Software refers to Computer parts, like projects, information, conventions, and so forth, that don’t have a material structure. As opposed to the actual equipment from which the framework is constructed, the product is that piece of a Computer framework comprising of encoded data or Computer guidelines.

It is here and there called “firmware” when the product is put away in equipment that can not be quickly changed, for example, with a BIOS ROM on an IBM Computer viable Computer.

Computer equipment and programming require one another, and neither of them can be sensibly utilized all alone. There are four fundamental parts of a broadly useful Computer: the number-crunching rationale unit (ALU), the control unit, the memory, and the I/O (all in all called information and result) gadgets.

Uses of Computer:

Computers are utilized in different fields, like homes, organizations, government workplaces, research associations, instructive establishments, medication, amusement, and so on due to their highlights and strong capacities. They have taken areas and organizations to an unheard of level.

  • Science-

Computers are the most ideal for the assortment, investigation, order, and capacity of information in science, exploration and designing. They likewise assist researchers with trading information both inside and universally with one another.

  • Government-

Computers in the public authority area are utilized to fill different roles and work on their administrations. Much of the time, information handling errands, the upkeep of residents’ data sets, and the advancement of a paperless climate are the main roles of utilizing Computers. What’s more, Computers assume a key part in the country’s safeguard framework.

  • Health and Medicine-

They are utilized to save data, records, live tolerant checking, X-beams, and more from patients. Computers help with setting up lab instruments, checking pulse and circulatory strain, and so on. Plus, Computers permit doctors to trade patient information with other clinical experts without any problem.

  • Education-

They assist individuals with getting different instructive materials, (for example, pictures, recordings, digital books, and so forth) in one spot. Likewise, Computers are the most appropriate for online classes, internet mentoring, online tests, and undertaking and task creation. Likewise, they can be utilized to keep up with and track understudy execution and different information.

  • Banking-

Most nations utilize internet banking frameworks so clients can get to their information straightforwardly. Individuals can check the equilibrium of their record, move money, and cover online bills, including charge cards. Additionally, banks use Computers to execute exchanges and store client data, exchange records, and so forth.

Short Computer Essay in English:

A Computer’s a programmable gadget that acknowledges crude data(input) and processes it as result with a gathering of directions (a program) to supply the outcome. It renders yield subsequent to performing numerical and sensible activities and can save the result for sometime later. “Computer” gets from “computare” in Latin, and that implies working out.

Types of Computer:

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

  • Micro Computers-

A solitary client Computer has less limit with regards to speed and capacity than different kinds. For a CPU, it utilizes a microchip. Computers, Computers, individual advanced aides (PDAs), tablets, and cell phones are normal instances of microcomputers. Microcomputers are for the most part planned and worked for general use, for example, perusing, data search, the web, MS Office, web-based entertainment, and so forth.

  • Mini Computers-

Minicomputers are likewise alluded to as “Midrange Computers.” They are multi-client Computers intended to help various clients all the while. Accordingly, they are by and large utilized by little organizations and firms.

  • Mainframe Computers-

It is additionally a multi-client Computer that huge organizations and government associations use to maintain their business activities as a lot of information can be put away and handled. Banks, colleges, and insurance agency, for instance, use centralized server Computers to store information from their clients, understudies, and policyholders.

  • Super Computer-

Among a wide range of Computers, supercomputers are the quickest and most exorbitant Computers. They have a tremendous limit with respect to capacity and processing speeds and can along these lines perform a large number of guidelines each second.

  • Workstations-

It is a solitary client Computer with a relatively more remarkable chip and a great screen contrasted with a smaller than normal Computer.

Benefits of Computers:

  • It increments efficiency.
  • It helps in associating with the web.
  • It helps in getting sorted out information and data.
  • It permits putting away a lot of information.

Fun Facts About Computers:

  1. The primary electric Computer that was imagined weighed around 27 tons or much more than that and took up to 1800 square feet.
  2. There are around 5000 new infections that are delivered consistently.
  3. The first name of Windows was Interface Manager.


It is definitely realized that the existence of people could not have possibly been so natural in the event that Computers were not a piece of human existence.

This is likewise upheld by a ton of bits of proof where we could find in day to day existence how the Computer isn’t simply present in an association but at the same time is accessible solidly in the pockets of everybody.
