Introduction to Information Technology
What is information Technology?
Information technology (IT) is the application of computers and telecommunications
equipment to store, retrieve, transmit and manipulate data, often in the context of a
business or other enterprise. 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.

In a business context, the Information Technology Association of America has defined
information technology as "the study, design, development, application, implementation,
support or management of computer-based information systems". The responsibilities of
those working in the field include network administration, software development and
installation, and the planning and management of an organization's technology life cycle,
by which hardware and software is maintained, upgraded and replaced.
Information Technology facilities ensure that information is available even during disaster
Humans have been storing, retrieving, manipulating and communicating information since
the Sumerians in Mesopotamia developed writing in about 3000 BC, 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)." 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). We shall look at some of the inventions associated with these
