A computer is an electronic machine that processes information—in other words, an information processor: it takes in raw information (or data) at one end, stores it until it's ready to work on it, chews and crunches it for a bit, then spits out the results at the other end. All these processes have a name.

A general purpose computer has four main components: the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by buses, often made of groups of wires.

System software runs the hardware and computer system. The two main categories of system software are operating systems and utility software. Functions of system software are: The three major functions of system software are allocating system resources, monitoring system activities, and disk and file management.
