Analysis of information sources in references of the Wikipedia article "Nibble" in English language version.
A data symbol represents one quartet (4 bits) of binary data.
Each hex digit (0–f) represents exactly 4 bits.
[...] The characteristic eight bit field is sometimes referred to as a byte, a four bit field can be referred to as a nibble. [...]
[...] Bit – The smallest unit of information which can be represented. (A bit may be in one of two states I 0 or 1). [...] Byte – A group of 8 contiguous bits occupying a single memory location. [...] Character – A group of 4 contiguous bits of data. [...](NB. This Intel 4004 manual uses the term character referring to 4-bit rather than 8-bit data entities. Intel switched to use the more common term nibble for 4-bit entities in their documentation for the succeeding processor 4040 in 1974 already.)
