Videoconferencing is the conduct of a videoconference (also known as video conferencing or videoteleconference)
by a set of telecommunication technologies which allow two or more locations to communicate with simultaneous
Two-way video and audio transmission. It has also been called 'visual collaboration and is a type of groupware.
Videoconferencing is different from video phone calls because it is designed to serve a conference or locations
rather than individuals.
It is an intermediate form of videotelephony, first used commercially in Germany
the late 1930s and later in the United States in the early 1970s as part of the development of the AT & T Picturephone
technology. With the introduction of relatively low cost, service, high-capacity broadband telecommunications in the 1990s, coupled with a powerful computer processors and video compression techniques, video conferencing has made significant progress in business, education, medicine and media. Like all long-distance communication technologies (such as mobile and Internet), by reducing the need to travel to bring people together technology also contribute to the reduction of carbon emissions, thereby helping to reduce global warming.
