Data processing system - Definition and Overview

In data processing, a Data Processor or Data Processing System is a system which processes information after it has been encoded into data.

A data processor is a specialized form of an information processing system. Its chief difference is that the inputs to a data processing system are converted from information into data by a process called encoding prior to being processed and as a result, must run the processed data through a decoding process before the information can be output from the system.
