In Computer science and information science, the word bit can have different meanings:
- A digit in binary notation, either 0 or 1. This is like a light switch; either there is light or there is not.
- A unit of measurement for the amount of data. This will be a multiple of 1 bit; only integers are allowed.
- As a unit of measurement for information. In this context, 1 bit is the amount of information that is present in the selection of two equally probable options. In this meaning, real values as multiples are possible.
A small amount of anything, either physical or theorized.
When talking about storage space, 8 bits are usually called a byte.
