![]() The term is commonly used as a synonym for computers and computer networks, but it also encompasses other information distribution technologies such as television and telephones. We shall call it information technology (IT)." Their definition consists of three categories: techniques for processing, the application of statistical and mathematical methods to decision-making, and the simulation of higher-order thinking through computer programs. Whisler commented that "the new technology does not yet have a single established name. Īlthough humans have been storing, retrieving, manipulating, and communicating information since the earliest writing systems were developed, the term information technology in its modern sense first appeared in a 1958 article published in the Harvard Business Review authors Harold J. An information technology system ( IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system - including all hardware, software, and peripheral equipment - operated by a limited group of IT users, and an IT project usually refers to the commissioning and implementation of an IT system. IT forms part of information and communications technology (ICT).
