In computing, a nibble (often nybble or even nyble to match the vowels of byte) is a four-bit aggregation, or half an octet. As a nibble contains 4 bits, there are sixteen (24) possible values, so a nibble corresponds to a single hexadecimal digit (thus, it is often referred to as a "hex digit" or "hexit").
A full byte (octet) is represented by two hexadecimal digits; therefore, it is common to display a byte of information as two nibbles. The nibble is often called a "semioctet" or a "quartet" in a networking or telecommunication context. Sometimes the set of all 256 byte values is represented as a table 16×16, which gives easily readable hexadecimal codes for each value.

Famous quotes containing the word nibble:
“Living, just by itself—what a dirge that is! Life is a classroom and Boredom’s the usher, there all the time to spy on you; whatever happens, you’ve got to look as if you were awfully busy all the time doing something that’s terribly exciting—or he’ll come along and nibble your brain.”
—Louis-Ferdinand Céline (1894–1961)
