What is a Bit in Computing?

A bit (binary digit) is the smallest unit of data that a computer can process and store.

A bit is always in one of two physical states, similar to an on/off light switch.

The state is represented by a single binary value, usually a 0 or 1.

However, the state might also be represented by yes/no, on/off or true/false.
