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. Such devices were historically referred to as machines in the UK.
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).
