What is VLAN ?

Answer Posted / zgeorgem

Sunilbaglur's answer is right...but this is a software
implementation... there is also a hardware implementation on
switches.... and since Cisco is asking about it this might
be the right answer

VLAN on switches is a feature that allows u to use a single
switch to logically divide their ports so that we can have
different networks on them...

for example if a switch has 32 ports then we can logically
separate 8 ports for network A (or LAN A)
8 ports for network B (or LAN B)
8 ports for network C (or LAN C)
8 ports for network D (or LAN D)

Since switches by default breakup collision domains, VLAN is
a way for them to act like routers by breaking up the
broadcast domain too...
