Digital denotes information represented in discrete values, typically binary digits 0 and 1, rather than continuous signals. In computing, telecommunications, and media, digital systems encode, store, process, and transmit data as sequences of bits.

Digital data can be copied and transmitted with minimal loss, and it enables error detection, compression, encryption,
