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).
