Video conferencing (VC) is the conduct of a video conference (also known as a video conference or video teleconference) by a set of telecommunication technologies which allow two or more locations to communicate by simultaneous two-way video and audio transmissions. It has also been called ‘visual collaboration’ and is a type of groupware.
Videoconferencing differs from videophone calls in that it’s designed to serve a conference or multiple locations rather than individuals. Some authors who cannot come physically to attend conference due to some reasons they can join Conference by Video Conference. Authors are welcome to give their presentations on SKYPE.
