What are the main reasons for using videoconferencing?
Videoconferencing can be used to hold meetings, to carry out interviews, to give seminars, to teach. Videoconferencing was initially developed to permit meetings to take place between people some distance apart, and its commercial viability depends upon it being cheaper and more convenient than traveling. When videoconferencing is used for teaching, it is often more effective for small groups of students at each site. It is also possible to share computer applications over videoconferencing links to enable participants to examine diagrams and documents at each site and to make changes as required.
