What is "IT"? Information Technology Defined

The term “Information Technology,” or IT, in its most basic definition is “the branch of engineering that deals with the use of computers and telecommunications to retrieve and store and transmit information.”

The term "Information and Communication Technologies," or ICT, is in wide spread use and, for all intents and purposes, can be used interchangeably with IT. The term is somewhat more common outside of the United States.

(b) All related services, including feasibility studies, systems design, software development, system testing, external off-site storage, and network services, whether provided by state employees or by others;

(c) The systems, programs, routines, and processes used to employ and control the capabilities of data processing hardware, including operating systems, compilers, assemblers, utilities, library routines, maintenance routines, applications, application testing capabilities, storage system software, hand-held device operating systems, and computer networking programs; and

(d) The application of electronic information processing hardware, software, or telecommunications to support the business processes of enterprise or government.

And, ICT (information and communications technology - or technologies) is an umbrella term that includes any communication device or application, encompassing: radio, television, cellular phones, computer and network hardware and software, satellite systems and so on, as well as the various services and applications associated with them, such as videoconferencing and distance learning.
