What is a bit?

Answer 1

Answer

Depends on the circumstances.

For computers a bit is the smallest possible unit of digital information, because it can have only two values, which can be interpreted as ON and OFF, or numerically as 0 and 1. You can group eight bits together with each one independently ON or OFF. Taken together, there 256 ON/OFF combinations, so they can represent the numbers from 0 to 255 or from -128 to +127, for example. The groups of eight are called bytes, and computer memories are organized in bytes.
