The term information technology (IT) came into common use in the late 1980s, supplanting earlier terms such as electronic data processing systems (EDP), management information systems (MIS), and office systems (IS). Oliver, E. C., Chapman, R. J. and French, C. S. (1990) defined IT as the technology which supports activities involving the creation, storage, manipulation and communication of information (principally computing, electronics and electronic communications) together with their related methods, management and applications. Such an all-embracing term is clearly open to a number of interpretations depending on in which context it is used. In some contexts, the term “information technology” means computers, ancillary equipment, software and firmware (hardware) and similar procedures, services (including support services) and related resources. Also, it includes any equipment or interconnected system or subsystem of equipment that is used in the automatic acquisition, storage, manipulation, management, movement, control, display, switching, interchange, transmission or reception of data or information.
