Introduction of Multimedia



Our computer understands only a digital language ie. 0 or 1.

The CPU (Central Processing Unit) understands a language of electrical phenomena.

When we say electrical phenomena, it means, it is a state when electric current passes and a state when no current passes.

A state when an electric current passes is called as 1 and a state when no current passes are called as state 0.

This electrical signal language of 0’s and 1’s is called the digital language.
