a system of representing information where the values are discontinuous, as opposed to analogue systems which are continuous. The most obvious example I can think of to illustrate this concept is the difference between 'traditional' radios (and early televisions) where the user has to tune into a station by a process of trial and error and a tiny movement of the dial can cause a distortion of the sound, and digital radios and televisions where the user simply selects a station or channel with no opportunity for variations in the signal: the station is either on or off.
'Digital culture' refers to the implications of a society increasingly dominated by digital technology.
