ICT means
Information and communications technology
From Wikipedia, the free encyclopedia
Information and communications technology (ICT) is often used as an extended synonym or as an umbrella term for information technology (IT), but is a more specific term (i.e. more broad in scope) that stresses the role of unified communications[1] 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.[2]
The term ICT is also used to refer to the convergence of audio-visual and telephone networks with computer networks through
a single cabling or link system. There are large economic incentives
(huge cost savings due to elimination of the telephone network) to merge
the telephone network with the computer network system using a single
unified system of cabling, signal distribution and management.
However, ICT has no universal definition, as "the concepts, methods and
applications involved in ICT are constantly evolving on an almost daily
basis."[3] The
broadness of ICT covers any product that will store, retrieve,
manipulate, transmit or receive information electronically in a digital
form, e.g. personal computers, digital television, email, robots;"
therefore, "one can say that ICT is concerned with the storage,
retrieval, manipulation, transmission or receipt of digital data."[3] More
importantly, ICT delineates how these various forms of digital mediums
interact with one another to, for example, meet a specified goal.
Etymology[edit]
The phrase "information and communication technology" has been used by academic researchers since the 1980s,[4] and the abbreviation ICT became popular after it was used in a report to the UK government by Dennis Stevenson in 1997,[5] and in the revised National Curriculum for England, Wales and Northern Ireland in 2000. But in 2012, the Royal Society recommended that ICT should no longer be used in British schools "as it has attracted too many negative connotations",[6] and with this being in effect since 2014 the National Curriculum began to utilize the word computing, which reflects the addition of computer programming into the curriculum.[7] A
leading group of universities consider ICT to be a soft subject and
thus advise students against studying A-level ICT, preferring A-level
Computer Science instead.[8]
Monetization of ICT[edit]
The money spent on IT worldwide has been most recently estimated as US
$3.5 trillion and is currently growing at 6% per year – doubling every
15 years. The 2014 IT budget of US federal government is nearly $82
billion.[9] IT
costs, as a percentage of corporate revenue, have grown 50% since 2002,
putting a strain on IT budgets. When looking at current companies’ IT
budgets, 75% are recurrent costs, used to “keep the lights on” in the IT
department, and 25% are cost of new initiatives for technology
development.[10]
The average IT budget has the following breakdown:[10]
- 31% personnel costs (internal)
- 29% software costs (external/purchasing category)
- 26% hardware costs (external/purchasing category)
- 14% costs of external service providers (external/services).
