In information theory, we define “digital data” as the discrete, discontinuous representation of information, in form of 0s and 1s. Any file stored on your computer hard disc is always stored in form of binary string consisting 0s and 1s like 010000100010101010…… For example, an image of size 1kb would have 1000 bytes of information that is equivalent to 8000 bits of information in a long string consisting 8000 0s and 1s. 

What is bit, byte etc? Bit stands for BInary digiT represented by either 0 or 1. A byte consist of 8 bits made up of only 0s and 1s. It takes 1 byte or 8 bits to store single alphabetic charachter.

This representation of data in computer technology has given rise to trend of using word “digital” with other words to give it a modernized resonance. For example, digital art, digital illustration, digital media, digital marketing and last but not the least digital callout.
