Information Technology –  definition

Information technology (IT) is the use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, store, secure and exchange all forms of electronic data.

Information technology (IT)  is a term that encompasses all forms of technology used to create, store, exchange and utilize information in its various forms including business data, conversations, still images, motion pictures and multimedia presentations .

Information technology (IT) is  the technology involving the development, maintenance, and use of computer systems, software, and networks for the processing and distribution of data.

Information Technology (IT) is the use of hardware, software, services, and supporting infrastructure to manage and deliver information using voice, data, and video.

Typically, Information technology (IT) is used in the context of enterprise operations as opposed to personal or entertainment technologies. The commercial use of IT encompasses both computer technology and telephony.

The term information technology was coined by the Harvard Business Review in 1958, in order to make a distinction between purpose-built machines designed to perform a limited scope of functions and general-purpose computing machines that could be programmed for various tasks. As the IT industry evolved from the mid-20th century, it encompassed transistors and integrated circuits -- computing capability advanced while device cost and energy consumption fell lower, a cycle that continues today when new technologies emerge.

To further define Information Technology and what should be included as far as the IT budget, the following information is provided.

What does Information Technology includes?

Information Technology includes :

*     All computers with a human interface.

*     All computer peripherals which will not operate unless connected to a computer or network.

*     All voice, video and data networks and the equipment, staff and purchased services necessary to operate them.

*     All salary and benefits for staff whose job descriptions specifically includes technology functions, i.e. network services, applications development, systems administration.

*     All technology services provided by vendors or contractors.

*     All licensing and maintenance of software.

*     Operating costs associated with providing information technology

*     All costs associated with developing, purchasing, licensing or maintaining software

Agencies may wish to include other costs at their discretion.

Examples of Information Technology are

*   Telephone and radio equipment and switches used for voice communications.

*   Traditional computer applications that include data storage and programs to input, process and output the data.

*   Software and support for office automation systems such as word processing and spreadsheets, as well as the computer to run them.

*   User, PCs & software.

*   Data networks and all associated communications equipment such as servers, bridges, routers, hubs & wiring.

*   Peripherals directly connected to computer information systems used to collect or transmit audio, video or graphic information, such as scanners and digitizers.

*   Voice response systems that interact with a computer database or application.

*   Video conferencing equipment.

*   The state radio communications network.

*   Computers and network systems used by teachers, trainers and students for educational purpose.

*   “Open” computer systems that monitor or automate mechanical or chemical processes and also store information used by computer applications for analysis and decision making.

*   All operating costs, equipment and staff time associated with supporting the technology infrastructure of the agency, possibly including items excluded above, such as video equipment used for technology training that is included in the information systems costs center for the agency.
