Information technology
Information and communication technology spending in 2005Information Technology
(IT), as defined by the Information Technology Association of America (ITAA) is:
"the study, design, development, implementation, support or management 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 convert, store, protect, process, transmit and retrieve
information, securely. In this definition, the term "information" can usually be
replaced by "data" without loss of meaning. Recently it has become popular to
broaden the term to explicitly include the field of electronic communication so
that people tend to use the abbreviation ICT (Information and Communication
Technology).
The term "information technology" came about in the 1970s. Its basic concept,
however, can be traced back even further. Throughout the 20th century, an
alliance between the military and various industries has existed in the
development of electronics, computers, and information theory. The military has
historically driven such research by providing motivation and funding for
innovation in the field of mechanization and computing.The first commercial
computer was the UNIVAC I. It was designed by J. Presper Eckert and John Mauchly
for the U.S. Census Bureau. The late 70s saw the rise of microcomputers,
followed closely by IBM's personal computer in 1981. Since then, four
generations of computers have evolved. Each generation represented a step that
was characterized by hardware of decreased size and increased capabilities. The
first generation used vacuum tubes, the second transistors, and the third
integrated circuits. The fourth (and current) generation uses more complex
systems such as Very-large-scale integration.
Information technology today
Today, the term Information Technology has ballooned to encompass many aspects
of computing and technology, and the term is more recognizable than ever before.
The Information Technology umbrella can be quite large, covering many fields. IT
professionals perform a variety of duties that range from installing
applications to designing complex computer networks and information databases. A
few of the duties that IT professionals perform may include: Data Management,
Computer Networking, Database Systems Design, Software design, Management
Information Systems,
Systems management.
World Information Technology and Services Alliance (WITSA) is a consortium of
over 60 information technology (IT) industry associations from economies around
the world. Founded in 1978 and originally known as the World Computing Services
Industry Association, WITSA has increasingly assumed an active advocacy role in
international public policy issues affecting the creation of a robust global
information infrastructure. Learn Information Technology, SCHOOLS Information
