The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.
Wi-Fi ( / ˈwaɪfaɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

The phrase "information and communication technologies" has been used by academic researchers since the 1980s. The abbreviation "ICT" became popular after it was used in a report to the UK government by Dennis Stevenson in 1997, and then in the revised National Curriculum for England, Wales and Northern Ireland in 2000. However, in 2012, the Royal ...
The money spent on IT worldwide has been estimated as US$3.8 trillion 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). The 2014 IT budget of the US federal government was nearly $82...
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 zetta bytes in 2014. This is the informational equivalent to 1.25 stacks of CD-ROM from the earth to the moon in 2007, and the equivalent of ...
The ICT Development Index ranks and compares the level of ICT use and access across the various countries around the world.In 2014 ITU (International Telecommunication Union) released the latest rankings of the IDI, with Denmark attaining the top spot, followed by South Korea. The top 30 countries in the rankings include most high-income countries ...

There is evidence that, to be effective in education, ICT must be fully integrated into the pedagogy. Specifically, when teaching literacy and math, using ICT in combination with Writing to Learn produces better results than traditional methods alone or ICT alone.The United Nations Educational, Scientific and Cultural Organisation (UNESCO), a divis...
Applications of ICTs in science, research and development, and academia include: 1. Internet research 2. Online research methods 3. Science communicationand communication between scientists 4. Scholarly databases 5. Applied metascience
Scholar Mark Warschauer defines a "models of access" framework for analyzing ICT accessibility. In the second chapter of his book, Technology and Social Inclusion: Rethinking the Digital Divide, he describes three models of access to ICTs: devices, conduits, and literacy. Devices and conduits are the most common descriptors for access to ICTs, but ...
Progress during the century
In the early 21st century a rapid development of ICT services and electronical devices took place, in which the internet servers multiplied by a factor of 1000 to 395 million and its still increasing. This increase can be explained by moores law, which states, that the development of ICT increases every year by 16-20%, so it will double in numbers every four to five years. Alongside this development and the high investments in increasing demand for ICT capable products, a high environmental i...
Implication
To tackle the environmental issues of ICT, the EU commission plans proper monitoring and reporting of the GHGemissions of different ICT platforms, countries and infrastructure in general. Further the establishment of international norms for reporting and compliance are promoted to foster transparency in this sector. Moreover it is suggested by scientists to make more ICT investments to exploit the potentials of ICT to alleviate CO2-emissions in general, and to implement a more effective coord...
In problem-solving
ICTs could also be used to address environmental issues, including climate change, in various ways, including ways beyond education.
A computer network is a set of computers sharing resources located on or provided by network nodes.Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of ...
