INPUTThe user enters the data by using an input device (such as keyboard, mouse) electronically and is processed by the processor.

PROCESSData is manipulated to process or transform it into information in the processing operation.

STORAGEThe storage (such as hard disk, compact disc (CD), diskettes) holds data, information and
