VC 
Logical circuit created to ensure reliable communication between two network 
devices. A virtual circuit is defined by a VPI/VCI pair, and can be either permanent

VID 
VLAN ID. The identification of the VLAN, which is used by the standard 802.1Q. 
Being on 12 bits, it allows the identification of 4096 VLANs. 
 
VLAN 
Virtual LAN. Group of devices on one or more LANs that are configured (using 
management software) so that they can communicate as if they were attached to 
the same wire, when in fact they are located on a number of different LAN 
segments. Because VLANs are based on logical instead of physical connections, 
they are extremely flexible.
