A nibble (also known as a nybble or nyble) can represent half a character(two nibbles are needed for a valid ASCII character).

A nibble is made up of 4 bits and those 4 bits are usually represented by a single hexadecimal value. 4 bits only allows for 16 combinations, 8 bits allows for 255.

An ASCII character is represented by two hexadecimal characters, which is the same as 8 bits or two nibbles.
