Data Flow • Input device- allows the user to enter data manually • Main memory- temporarily stores data entered by the user [i.e. the RAM] • CPU- processes data transferred from main memory and returns the results it calculates back to main memory • Output device – displays results of the processed data as information [e.g. on a monitor] • Backing storage – more permanently loads and saves data [e.g. hard disk drive]
