Information technology

Information technology, is the study, design, development, implementation, support or administration of computer based information systems, particularly software applications and computer hardware.In short, IT deals with the use of electronic computers and computer software to transfer, store, protect, process, transmit and get back information, securely.

In this definition, the term information can frequently be replaced by data without loss of meaning. Recently it has become popular to widen the term to explicitly consist of the field of electronic communication so that people tend to use the abbreviation ICT (Information and Communication Technology). Strictly speaking, this name contains some redundancy.

Today, the term Information Technology has distended to encompass many aspects of computing and technology, and the term is more identifiable than ever before. The Information Technology umbrella can be quite large, covering many fields. IT professionals achieve a variety of duties that range from installing applications to designing complex computer networks and information databases.
