ICT is also used to refer to the convergence of audiovisual and telephone networks with computer networks through a single cabling or link system. There are large economic incentives to merge the telephone network with the computer network system using a single unified system of cabling, signal distribution, and management. ICT is an umbrella term that includes any communication device, encompassing radio, television, cell phones, computer and network hardware, satellite systems and so on, as well as the various services and appliances with them such as video conferencing and distance learning. ICT also includes analog technology, such as paper communication, and any mode that transmits communication.[2]
ICT is a broad subject and the concepts are evolving.[3] It covers any product that will store, retrieve, manipulate, transmit, or receive information electronically in a digital form (e.g., personal computers including smartphones, digital television, email, or robots). Skills Framework for the Information Age is one of many models for describing and managing competencies for ICT professionals for the 21st century.[4]
Etymology
The phrase "information and communication technologies" has been used by academic researchers since the 1980s.[5] The abbreviation "ICT" became popular after it was used in a report to the UK government by Dennis Stevenson in 1997,[6] and then in the revised National Curriculum for England, Wales and Northern Ireland in 2000. However, in 2012, the Royal Society recommended that the use of the term "ICT" should be discontinued in British schools "as it has attracted too many negative connotations".[7] From 2014, the National Curriculum has used the word computing, which reflects the addition of computer programming into the curriculum.[8]
Variations of the phrase have spread worldwide. The United Nations has created a "United Nations Information and Communication Technologies Task Force" and an internal "Office of Information and Communications Technology".[9]
Monetization
The money spent on IT worldwide has been estimated as US$3.8 trillion [10] in 2017 and has been growing at less than 5% per year since 2009. The estimate 2018 growth of the entire ICT is 5%. The biggest growth of 16% is expected in the area of new technologies (IoT, Robotics, AR/VR, and AI).[11]
The average IT budget has the following breakdown:[13]
31% personnel costs (internal)
29% software costs (external/purchasing category)
26% hardware costs (external/purchasing category)
14% costs of external service providers (external/services).
The estimate of money to be spent in 2022 is just over US$6 trillion.[14]
Technological capacity
The world's technological capacity to store information grew from 2.6 (optimally compressed) exabytes in 1986 to 15.8 in 1993, over 54.5 in 2000, and to 295 (optimally compressed) exabytes in 2007, and some 5 zettabytes in 2014.[15][16] This is the informational equivalent to 1.25 stacks of CD-ROM from the earth to the moon in 2007, and the equivalent of 4,500 stacks of printed books from the earth to the sun in 2014. The world's technological capacity to receive information through one-way broadcast networks was 432 exabytes of (optimally compressed) information in 1986, 715 (optimally compressed) exabytes in 1993, 1.2 (optimally compressed) zettabytes in 2000, and 1.9 zettabytes in 2007.[15] The world's effective capacity to exchange information through two-way telecommunication networks was 281 petabytes of (optimally compressed) information in 1986, 471 petabytes in 1993, 2.2 (optimally compressed) exabytes in 2000, 65 (optimally compressed) exabytes in 2007,[15] and some 100 exabytes in 2014.[17] The world's technological capacity to compute information with humanly guided general-purpose computers grew from 3.0 × 10^8 MIPS in 1986, to 6.4 x 10^12 MIPS in 2007.[15]
