Virtual Connection (VC)

A link that seems and behaves like a dedicated point-to-point line or a system that delivers

packets in sequence, as happens on an actual point-to-point network. In reality, the data is

delivered across a network via the most appropriate route. The sending and receiving

devices do not have to be aware of the options and the route is chosen only when a

message is sent. There is no pre-arrangement, so each virtual connection exists only for

the duration of that one transmission.

WAN

Wide area network - A data communications network that spans any distance and is usually

provided by a public carrier (such as a telephone company or service provider).
