Information
technology (IT) is the use of computers to store,
retrieve, transmit, and manipulate data or information, often in the context
of a business or other enterprise. IT is considered to be a subset of information and communications technology (ICT).
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 users.
