This document provides an overview of computer-based information systems. It defines a computer system as a combination of data/information, people, procedures, hardware, and software. It describes computers as electromechanical devices that require software to be useful. The document also distinguishes between data, which are raw facts and figures, and information, which is processed or summarized data. It lists several types of data including numeric, textual, audio-visual, and physical data. It defines computer professionals and end users or regular users of computers. Finally, it discusses operating procedures and emergency procedures for using computer hardware and software correctly.
