What is VLAN ?

Answer Posted / venkatesh

VLAN is Short for virtual LAN, a network of computers that
behave as if they are connected to the same wire even
though they may actually be physically located on different
segments of a LAN. VLANs are configured through software
rather than hardware, which makes them extremely flexible.
One of the biggest advantages of VLANs is that when a
computer is physically moved to another location, it can
stay on the same VLAN without any hardware reconfiguration.
