Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of data[1] and information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies.[2] IT forms part of information and communications technology (ICT).[3] 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.
