Information Technology (IT) Is The Use of

IT is the use of computers to store, retrieve, transmit, and manipulate data or information, typically within a business context rather than personal use. IT systems generally include all computer hardware, software, and peripherals operated by a limited group of users. While humans have been storing, retrieving, and communicating information since ancient Sumerians developed writing, the term "information technology" first appeared in a 1958 article defining it as techniques for processing data, applying statistics to decision making, and simulating higher-order thinking through computer programs. IT is commonly used synonymously with computers and networks but also encompasses other information distribution technologies like television and phones.

Information technology (IT) is the use of computers to store, retrieve, transmit, and

manipulate data[1] or information. IT is typically used within the context of business operations as


opposed to personal or entertainment technologies.[2] 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.
Humans have been storing, retrieving, manipulating, and communicating information since
the Sumerians in Mesopotamia developed writing in about 3000 BC,[3] but the term information
technology in its modern sense first appeared in a 1958 article published in the Harvard Business
Review; authors Harold J. Leavitt and Thomas L. Whisler commented that "the new technology does
not yet have a single established name. 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.[4]
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. Several
products or services within an economy are associated with information technology,
including computer hardware, software, electronics, semiconductors, internet, telecom equipment,
and e-commerce.[5][a]
Based on the storage and processing technologies employed, it is possible to distinguish four
distinct phases of IT development: pre-mechanical (3000 BC – 1450 AD), mechanical (1450–
1840), electromechanical (1840–1940), and electronic (1940–present).[3] This article focuses on the
most recent period (electronic).
