The document discusses video conferencing (VC), including its definition, types, and uses. VC allows for audio and video communication between two or more locations. There are two main types: point-to-point VC between two locations, and multipoint VC between three or more locations using a central server. VC can be done from dedicated conference rooms or individual desktops. It has advantages like saving travel costs and time, but disadvantages like needing good internet and equipment. The document lists many applications of VC like education, medicine, banking, and more.
