What is Computer?

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, or 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 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 the 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.) help 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:-

block diagram of computer
  • 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.

For a better understanding of the topic, we had given a brief explanation of the hardware and software of a computer with examples.
