digital

In electronics and computing, a term meaning ‘coded as numbers’. A digital system uses two-state, either on/off or high/low voltage pulses, to encode, receive, and transmit information. A digital display shows discrete values as numbers (as opposed to an analogue signal, such as the continuous sweep of a pointer on a dial).

Digital electronics is the technology that underlies digital techniques. Low-power, miniature, integrated circuits (chips) provide the means for the coding, storage, transmission, processing, and reconstruction of information of all kinds.
