Information technology (IT) is the use of computers and telecommunications equipment to store, retrieve, transmit and manipulate data.
In a business context, the Information Technology Association of America has defined information technology (IT) as "the study, design, development, application, implementation, support or management of computer-based information systems".
[Proctor 2011, preface]
Several industries are associated with information technology, such as computer hardware, software, electronics, semiconductors, internet, telecom equipment and computer services.
