What is digit?

A digit is a single numeral used to represent any of the numbers from 0 to 9. It is also used to represent a character in a digital code or binary language, where each digit represents a binary value of either 0 or 1. Digits are essential building blocks for modern computing and digital communication, as they allow data to be represented in a standardized format that can be easily stored, processed, and transmitted. The term ‘digit’ comes from the Latin word ‘digitus,’ which means ‘finger,’ as fingers were traditionally used to count numbers on one’s hand.
