Computer Full Form, Meaning, and Basic Knowledge for Exams!

A computer is an electronic device that aids in the calculation of arithmetic and logical equations. The arithmetic and logical unit (ALU) of a computer are one of its most notable features. This electronic machine is also equipped with memory. This aids in the storage of information. Depending on the technology, computers can be classified as digital, analog, or hybrid.


There are various other types of computers, such as the supercomputer, personal computers, desktops, laptops, and so forth. A computer is also referred to as a programming machine because it is unable to perform any functions unless it has been programmed.

It accepts raw data from the user as input, processes it, and then returns the results to the user. A computer is a digital electronic machine that can be programmed to carry out sequences of arithmetic or logical operations (computation) automatically.

Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a “complete” computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for “full” operation.

This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster.

Definition of Computer

The computer is not an acronym; rather, it is a word derived from the word “compute,” which literally means to calculate in English. Consequently, in layman’s terms, a computer is an electronic device that is used for high-speed calculation. Check out more: IGTOK: How To Increase Instagram Followers Through This App!

Some people believe that COMPUTER is an abbreviation for Common Operating Machine Designed for Technological and Educational Research, which is correct. It is a myth for two reasons: first, this definition does not make any sense, and second, when computers were first invented, they were simply calculating machines that required a large amount of space to be set up and operate.

“A computer is a general-purpose electronic device that is used to perform arithmetic and logical operations automatically. A computer consists of a central processing unit and some form of memory.”

Mobile computers

Mobile Computers

The first mobile computers were heavy and ran from mains power. The 50 lb (23 kg) IBM 5100 was an early example. Later portables such as the Osborne 1 and Compaq Portable were considerably lighter but still needed to be plugged in. The first laptops, such as the Grid Compass, removed this requirement by incorporating batteries – and with the continued miniaturization of computing resources and advancements in portable battery life, portable computers grew in popularity in the 2000s. The same developments allowed manufacturers to integrate computing resources into cellular mobile phones by the early 2000s.

These smartphones and tablets run on a variety of operating systems and recently became the dominant computing device on the market. These are powered by System on a Chip (SoCs), which are complete computers on a microchip the size of a coin.

Categorization on the basis of technology

  1. Digital Computer
  2. Analog Computer
  3. Hybrid Computer

Categorization on the basis of generation

  • First-generation computers: (1940-1956) based on Vacuum tubes.
  • Second-generation computers: (1956-1963) based on Transistors
  • Third-generation computers: (1964-1971) based on Integrated Circuits
  • Fourth-generation computers: (1971- Present) Based on Microprocessors
  • Fifth-generation computers: (Present and Beyond) based on Artificial Intelligence

There are many types of computers available on the basis of their working areas: Supercomputers, work frames, personal computers, desktops, laptops, palmtops, etc.
