A computer to complete a job requires more than just the actual equipment or hardware we see and touch. It requires software – programs for directing the operation of a computer or electronic data.
Software is the final computer system component. These computer programs instruct the hardware how to conduct processing. The computer is merely a general-purpose machine which requires specific software to perform a given task. Computers can input, calculate, compare, and output data as information. Software determines the order in which these operations are performed.
Programs usually fall in one of two categories: system software and applications software.
