Topic 42. Storing Data
The processing stages of some systems may need to store data. The data, or information, is stored in the system to be used later.
The set-reset bistable is an example of a circuit that stores data.
It ‘remembers’ if the Set input has been made low since the bistable was last reset. Its output is a low voltage or a high one. We may write its output as ‘0’ (usually for ‘low’) or ‘1’. These are the two digits used for numbers in the binary system. The output of the bistable is a single BInary digiT, or BIT.
