Among the more significant events in the recent history of long-distance communication have been the building of computer-based communication networks and the development of technologies that have made possible the implementation and exploitation of these networks. In this chapter we focus on these technologies and on the challenges and opportunities for human factors research that they present. We begin with a brief historical overview of computer-communications networking technology. We then focus on current trends, especially the phenomenon of "global connectivity" that networking is coming to represent and some of the implications this could have.

Schools use a diverse set of ICT tools to communicate, create, disseminate, store, and manage information. When teachers are digitally literate and trained to use ICT, these approaches can lead to higher order thinking skills, provide creative and individualized options for students to express their understandings, and leave students better prepared to deal with ongoing technological change in society and the workplace. ICT issues planners must consider include: considering the total cost-benefit equation, supplying and maintaining the requisite infrastructure, and ensuring investments are matched with teacher support and other policies aimed at effective ICT use. Digital culture and digital literacy: Computer technologies and other aspects of digital culture have changed the ways people live, work, play, and learn, impacting the construction and distribution of knowledge and power around the world. Digital literacy—the skills of searching for, discerning, and producing information, as well as the critical use of new media for full participation in society—has thus become an important consideration for curriculum frameworks. In many countries, digital literacy is being built through the incorporation of information and communication technology ICT into schools. Some common educational applications of ICT include:.
Information technology IT is the use of computers to store, retrieve, transmit, and manipulate data  or information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. An information technology system IT system is generally an information system , a communications system , or, more specifically speaking, a computer system — including all hardware , software , and peripheral equipment — operated by a limited group of IT users. Leavitt and Thomas L. Whisler commented that "the new technology does not yet have a single established name. We shall call it information technology IT.
ICT includes all digital technology that assists individuals, businesses and organizations in using information. It covers all electronic products that deal with information in a digital form. Therefore, ICT is concerned with digital data storage, retrieval and transmission.
Information and communications technology ICT is an extensional term for information technology IT that stresses the role of unified communications  and the integration of telecommunications telephone lines and wireless signals and computers, as well as necessary enterprise software , middleware , storage and audiovisual, that enable users to access, store, transmit, and manipulate information. The term 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.
