Video Conferencing

What is Video Conferencing

Video conferencing has been used since the 1970s and is designed to connect groups, rather than individuals, through a simultaneous audio and video connection.  Each participant needs access to the internet as well as a webcam and screen, whether this is a computer, or via a plasma screen, and a microphone and set of speakers. 
Video conferencing is easier what you might think of as using a video phone. It just means people in two or more places (different rooms, cities, or countries) can see and hear each other using microphones, cameras, speakers and a TV or computer screen. It works by sending the sound and picture from the microphone and camera over the phone lines or internet.
