Technology has become an essential element of many sectors ranging from business to education as a means by which people connect, communicate and collaborate with one another; moreover, this type of connection is easy and accessible both locally and globally. Currently, web technologies have streamlined and strengthened links worldwide, allowing people to interact to distribute information and practices. There is no doubt that the second generation of the internet called Web 2.0 has been used by various sectors since businesses have become highly dependent on this technology which enables collaboration between reader and writer. Social networking (SN) is an example of one of the best aspects of the Web 2 revolution. Currently, educational institutions are in the process of introducing social networking as a teaching and learning tool by adopting a specific platform (i.e. wiki; blog; discussion board etc.) especially regarding assessments, as a means of improving students' personal skills (i.e. motivation; leadership; negotiation, communication, problem solving, time management, and reflection) and professional skills (i.e. reading. writing, research, information, critical thinking, decision making technology, digital oral presentation, visual representations and teamwork) to enhance students' learning in the academic environment and to prepare them for the workplace in the future. This chapter will examine and discuss the history of the Internet, the history of social networking and its various web types, and social networking applications which are relevant to and useful in the education sector.
