Nybble

A nybble (sometimes spelled nibble) is a set of four bits. Since a full byte is eight bits, a nybble is half a byte. It is sometimes called a half-byte or tetrade; in the context of computer networking, it is also called a semi-octet, quadbit, or quartet. The four bits in a nybble provide a set of 16 possible values.

A single nybble can be represented by one of the 16 hexadecimal digits (0-F); when shown this way, a nybble is called a hex digit. A full byte can be portrayed by a pair of hex digits (00-FF).

The table below lists all 16 possible nybbles, along with the corresponding hex digit.
