A '''data processing system''' is a combination of [[machine]]s<!-- "data processing" is specific to machines, there is no data but storage processing in nature, see the OED -->, people, and processes that for a set of [[Input/output|inputs]] produces a defined set of [[Input/output|outputs]]. The inputs and outputs are interpreted as [[data]], [[fact]]s, [[information]] etc. depending on the interpreter's relation to the system.
