(WAN)
A private long distance network that uses leased lines to connect computers or LANs. A
wide area network is a linking of computers not physically attached through conventional
network connectivity. Usually the WAN connection is a dedicated or high grade dial up
phone link. It is often done with T1 or T3 connections but can also be through satellite or
other technologies.
WINS Windows Internet Naming Service. A system that determines the IP address associated
with a particular network computer.
Virtual Connection (VC) A connection between two hosts in a packet-switching network. In this case, the two hosts
can communicate as though they have a dedicated connection even though the packets
might actually travel very different routes before arriving at their destination.
Virtual Local Area
Network (VLAN)
A VLAN consists of a network of computers that behave as if connected to the same wire,
though they may actually be physically connected to different segments of a LAN. VLANs
are configured through software rather than hardware, which makes them extremely
flexible.
