Talk:Central processing unit/Processor article history

A processor is a sub-system of an information processing system which processes or changes information received from an object in some manner prior to transmitting it to an observer.

Similarly, the processor sub-system of a data processing system processes received information after it has been encoded into data by the input sub-system. This data is then processed by the processing sub-system before being sent as data to the output sub-system where it is decoded back into information.

The two major types of digital processors are the central processing unit (CPU) and the digital signal processor (DSP).
