Virtual Networks
SUMMARY DEFINITION: Local Area Networks are created using hardware (cables). Virtual networks are created using software.
It's useful to remember that the whole LAN is still physically connected by cables, but the 'virtual network' of devices created through software are restricted from accessing any of the other computers on the LAN. Because of this they appear to be a completely separate network within the larger one.
