Information technology
Information technology (IT) is the application of computers and internet to store, retrieve, transmit, and manipulate data, or an information often in the context of a business or other enterprise.
Description
IT is considered a subset of information and communications technology (ICT).
In 2012, Zuppo proposed an ICT hierarchy where each hierarchy level "contain some degree of commonality in that they are related to technologies that facilitate the transfer of information and various types of electronically mediated communications."
Business/IT was one level of the ICT hierarchy.
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 industries are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, engineering, healthcare, e-commerce, and computer services.
