What is the full form of COMPUTER


The computer is not an acronym; it is a word derived from the word "compute", which means to calculate. So, in simple words, you can say that a computer is an electronic device that is used for fast calculation.

Some people say that COMPUTER stands for Common Operating Machine Purposely Used for Technological and Educational Research. It is only a myth because, first, this definition does not make any sense, and second, when the computer was invented, they were just calculating machines that needed a lot of space for establishment.

"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."

ALU: Arithmetic Logical Unit is used to carry out arithmetic and logical operation.

CU: Control unit is used to change the order of operations in response to stored information.

Categorization on the basis of technology

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

Categorization on the basis of generation

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

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

What components does a computer require to function?

All of the aforementioned elements are not necessary for a computer. However, a computer needs the components listed below in order to operate, at the very least.

Processor: A part that carries out commands from the hardware and software.

Memory: Temporary primary storage for information moving between the CPU and the storage.

Motherboard: The component that connects all other components is the motherboard.

Secondary storage device: Data is permanently stored on a slower secondary storage device (such as a hard disc).

To communicate with a computer that simply had the bare minimum of the aforementioned components, however, you would need to attach at least one input device (e.g., keyboard). In order to view what is happening, you would also require at least one output device, such as a monitor.
