Basics of Computer

First of all I would like to make things simple. This article contains the basic concept of the topic.

Computer:

Computer is a device which takes information from user as input and then produces a required information as output. It is also called as PC in regular use. PC stands for Personal Computer.

Computer does not only mean that we work on it by sitting in front of a screen. There are computers in early days which have no screen or mouse, for example

Astrolabe(used for navigation purpose) and Abacus(used as a math tool similar to calculator).

Desktop Computers
in 21st Century

Size of computer depends on the components used in making it. If the size of components are big, then the computer will eventually turn to be big.
But these days components used in computers got smaller and powerful, eventually computers became smaller and effective to use. They can work on different inputs given by the user at a same time and can produce efficient outputs in no time.
