Zero order hold is used in Digital - Analogue converters (DACs). It literally holds the digital signal for the sample time, then moves to the next digital sample and holds that signal for the sample time as well, in order to reconstruct the analogue signal.

A zero-order hold is a mathematical model of the practical signal reconstruction done by a conventional digital-to-analogue converter, describing the effect of converting a discrete-time signal to a continuous-time signal by holding each sample value for one sample interval.
