Information and communications technology (ICT) is a broad term for information technology (IT) that emphasizes the role of unified communications and the integration of telecommunications (telephone lines and wireless signals) and computing, as well as enterprise software, middleware, storage, and audiovisual that it Enabling users to access, store, transmit, understand and manipulate information.
ICT is a general term that encompasses all communication devices, including radio, television, mobile phones, computer and network hardware, satellite systems, etc., and the various services and devices that accompany. ICT also includes analogue technologies, such as communication on paper, and any mode that conveys the communication.
ICT is a broad topic and concepts are evolving. Includes any product that electronically stores, retrieves, manipulates, transmits or receives information in digital form. The Information Age Competency Framework is one of many models to describe and manage the competencies of 21st century ICT professionals.
The abbreviation "ICT" became popular after Dennis Stevenson used it in a 1997 report to the UK Government 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' be phased out in UK schools 'as it has evoked too many negative connotations'. As of 2014, the National Curriculum uses the word computer science reflecting the inclusion of computer programming in the curriculum.
Global IT spending was estimated at $3.8 trillion in 2017 and has been growing at less than 5% per year since 2009. Estimated growth for 2018 for all ICT is 5%. The largest growth of 16% is expected in the area of new technologies (IoT, robotics, AR/VR and AI).
The US federal government's IT budget was nearly $82 billion in 2014. IT costs as a percentage of business revenue have increased by 50% since 2002, putting pressure on IT budgets. Looking at enterprise IT budgets today, 75% are recurring costs used to “keep the lights on” in the IT department and 25% are costs for new technology development initiatives.
Global technological capacity to store information grew from 2.6 exabytes (optimally compressed) in 1986 to 15.8 in 1993, more than 54.5 in 2000, and to 295 exabytes (optimally compressed) in 2007 and around 5 zetta bytes in 2014. This is the information that in 2007 was equivalent to 1.25 stacks of CD-ROMs from Earth to the Moon, and in 2014 the equivalent of 4,500 stacks of printed books from Earth to Sun 432 exabytes of information (optimal compressed) in 1986, 715 exabytes (optimally compressed) in 1993, 1.2 zettabytes (optimally compressed) in 2000, and 1.9 zettabytes in 2007.
The effective global capacity for information exchange over two-way telecommunications networks was 281 petabytes of information (optimally compressed) in 1986, 471 petabytes in 1993, 2.2 exabytes (optimally compressed) in 2000, 65 exabytes (optimally compressed) in 2007 and about 100 exabytes in 2014. The global technological capacity to compute information with general-purpose human-operated computers increased from 3.0×10^8 MIPS in 1986 to 6.4×10^12 MIPS in 2007.
The ICT Development Index ranks and compares the level of use and access to ICT in different countries around the world. In 2014, the ITU (International Telecommunication Union) published the latest
