INFORMATION AND COMMUNICATIONS TECHNOLOGY
Information and Communications Technology or ICT,
is often used as an extended synonym for information technology (IT), but is a more
specific term that stresses the role of unified communications and the integration
of telecommunications (telephone
lines and wireless signals), computers as well as necessary enterprise software, middleware,
storage, and audio-visual systems, which enable users to access, store,
transmit, and manipulate information.
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. Several industries
are associated with information technology, such as computer
hardware, software, electronics, semiconductors,
internet,
telecom equipment, e-commerce
and computer services.
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.
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). This article focuses
on the most recent period (electronic), which began in about 1940.
The phrase ICT had been used by academic researchers
since the 1980s, but it became popular after it was used in a report to the UK
government by Dennis Stevenson in 1997
and in the revised National
Curriculum for England, Wales and Northern Ireland in 2000.
