A computer system has five major components: hardware, software, people, documentation, and data. Without any one of these components, there would be little or no purpose of the system. Of course, there is another version that identifies the input–process–output (IPOS) model, which consists of inputs, processing, outputs, and storage (referring to main memory, not disk drives).
