A video conference is a live, visual connection between two or more people residing in separate locations for the purpose of communication.
At its simplest, video conferencing provides transmission of static images and text between two locations.
At its most sophisticated, it provides transmission of full-motion video images and high-quality audio between multiple locations.
Video conferencing's main advantage over teleconferencing is that users can see each other, which allows them to develop stronger relationships. When a video conference is held for informal purposes, it is called a video call or video chat.
