Although the term did not evolve until the 1970s, it has been used to describe any technology engaged in the inputting, processing, storage, transmission, and retrieval of information, such as the codex, printing systems, facsimile machines, satellites, and others. The modern idea of information technology (IT), however, involves the use of computers and computer-based management information systems. This modern idea of IT advanced along with computers, which evolved from vacuum tubes to transistors to integrated circuits to the computer chip. Changes in IT have affected individuals, industries, and society in profound ways.
IT professionals are responsible for computer and computer network systems within their organizations. Careers in IT include database administration, systems analysis, system development and programming, and end-user computing. IT departments are considered a supporting activity within an organization. They can be either centralized, in which case an enterprise has a central IT department, or decentralized, in which case the various departments or divisions have their own IT departments or personnel. The latter structure offers greater flexibility and specialization. A centralized IT department, however, is generally more cost-effective.
