Data Output : Processed data is no use to you if you cannot use it. Once data has been processed, you will either:
(1) Send it as a data file to another system, e.g. write a file to disk, transmit a file over a phone link via a modem, etc. For example as e-mail..
(2) Send it to a peripheral where it is decoded into information that can be readily understood. The most common peripherals are visual display units (VDUs) or printers.
