Digital is a term used to describe computing devices in which the values of data are discrete, and can only take one of a small number of enumerated values; unlike analog devices in which infinitely variable levels are used as data.

The term is also used to describe circuits which operate in this mode; usually only two values are handled/supported ('high'/'low', 'true/false', '0'/'1', etc), and boolean logic is used (AND, OR, etc).
