A bit (binary digit) is the base unit of information and is the smallest unit in which there is sufficient discrimination to communication any information.
Overview
A bit is a universal unit consisting of just two states - e.g., 1 and 0, true and false, on and off, up and down, heads and tails, punched or not punched or any other system that can represent two states. The correlation between these values and the physical states of the underlying implementation is a matter of convention. Fundamentally, any form of information (e.g., text, sounds, pictures) can be represented in bits and be communicated over any system capable of being in just two states. A linear sequence of bits is called a binary string and the length of such sequence is known as a bit length.
