There are many full forms available on different websites, and there is no uniform single, widely agreed Computer Full Form.


What is Computer and its Components?

A computer is an electronic system that uses instructions to store, retrieve, and process data by using hardware and software.

It uses computer programming to perform arithmetical or logical operations sequences.

The computer contains particularly arithmetic and logical unit i.e. ALU.

Computers can be technology-based ie. It can be digital, analog, and hybrid.

There are also several other Super Computers, Personal Computers, Desktops, Laptops, etc.

The computer is often known to be a computing machine since, without software, it cannot do anything.

It takes user raw data as an input process and produces user output.

In simple words, we can say that the digital computer is an electronic device along with its components i.e. hardware and software (just like apps in mobile).

It makes our life easier by processing raw data output in any form given to it, into a meaningful data as desired by the user.

There is a lot of software and hardware are available in the market as per the user requirements.

How does the Computer work?

For complete function of the components two major components are required i.e. Hardware and Software.

The Hardware of a computer consists of two categories namely processing hardware and peripheral devices.

CPU falls under processing hardware which processes the data. While peripheral devices (Keyboard, Mouse, etc.) helps the user to interact with the computer.

We will discuss both hardware and software components down below in the article.

Block Diagram of the Computer

The working of the computer can be divided into the below mentioned four functions or steps:-

  • Input – It receives input in the form of data/information from the user with the help of various input devices like a scanner, keyboard, mouse, etc.
  • Processing Information/Data – It performs logical and Athematic operations on data/information.
  • Storage of Information – On successful processing of data the data/information is then stored in storage devices like Hard Disk, Pen Drive. CD etc.
  • Output – Lastly, the processed and final data/information is then received by the user through output devices like printers, monitors, etc.

Parts of Computer | Hardware, and Software

What is Hardware on a Computer?

Computer Hardware is the physical parts of the computer that we can touch, feel, and see for example CPU, Monitor, Mouse, Keyboard, and so on.

All the below mentioned are examples of the internal hardware of a computer:-

  • CPU – Central Processing Unit
  • Drive – Hard disk drive, CD-ROM, Floppy Drive, DVD
  • Motherboard
  • Fan
  • RAM- Random Access Memory
  • Sound Card
  • Video Card

All these below-mentioned are the best examples of the external hardware of a computer:-

External Hardware of Computer:-

  • Desktop
  • Keyboard
  • Projector
  • Scanner
  • Speaker

What is Software in Computer?

full form of computer - software

The software in a computer is a set of instructions or programs that tells the computer how to compute the raw data to get the desired output.

5 example of software that is most commonly used in a computer are:-

  • Internet Browser – Firefox, Google Chrome, Internet Explorer
  • Movie player – VLC and Windows Media Player
  • Operating System- Android, ios, Linux, macOS, and windows
  • Adobe photoshop
  • Microsoft office

Classification of the computer on the basis of technology:-

  • Analog Computer
  • Digital Computer
  • Hybrid Computer
  • Super Computer
  • Mainframe Computer
  • Mini Computer
  • Micro or Personal Computer

Laptops and Desktops are the best examples of micro or personal computer which we use in our daily life.

Classification of the Computer on the basis of Generations:-

The Generations of computers is defined on the basis of major technological changes:-

  • First Generation (1940-1956) – uses vacuum tubes, ENIAC was the first computer of this generation.
  • Third Generation (1964-1971)- ICs (integrated circuits) used in place of transistors which reduced the size of computers.
  • Fourth Generation (1972-2010) – uses microprocessors and ICs.
  • Fifth Generation (2010- present) – the fifth generation of computers uses AI (artificial intelligence) and some best examples of these are Siri on iPhone, Cortana on Windows 8, and 10.

Basic Application of Computer in Different Fields

The computer had become an integral part of our day-to-day life. We had mentioned below some of the basic application of computer for you:-

Full Forms of Computer Related Parts

Full form of CPU

The full form of CPU is:-

C – Central

P – Processing

U – Unit

A special region called the CPU (Central Processing Unit) socket is the area where the CPU is mounted within the motherboard to handle other device inputs and outputs.

It performs all of the basic arithmetical and logical operating operations and communicates the computer’s commands and programs.

The term CPU conventionally refers to a processor that includes the control unit and the logical arithmetic unit. CPU is sometimes called the computer brain.

Full form of ALU

A – Arithmetic

L – Logic

U – Unit is the complete full form of ALU.

Arithmetic logic unit abbreviation will be – The portion of a machine that performs all arithmetic computations.

The ALU is divided into two units in processors, an arithmetic unit (AU) and a logic unit (LU).

It represents the fundamental building block of a computer’s central processing unit (CPU). Modern CPUs contain highly potent, complex ALUs.

Full form of LAPTOP

A laptop or a laptop computer is, in simple words, a small portable device.

Full form of the laptop is:-

L – Lightweight

A – Analytical

P – Platform

T – with Total

  1. Hi! This is kind of off topic but I need some advice from
    an established blog. Is it hard to set up your own blog?
    I’m not very techincal but I can figure things out pretty quick.
    I’m thinking about creating my own but I’m not sure where to begin. Do you have
    any ideas or suggestions? Cheers

  2. I really loved reading your blog. I also found your posts very interesting. In fact after reading, I had to go show it to my friend and he ejoyed it as well!

  3. thanks for sharing this great information. Computer is not an acronym, it is a word derived from a word “compute” which means to calculate. So, in simple words you can say that computer is an electronic device which is used for fast calculation. To know more about Full Form of Computer
