virtual path identifier and virtual circuit identifier
The answer depends on what exactly you mean by VC: virtual channel, virtual circuit or something else.
Difference between a PVC-Permanent Virtual Circuit and SVC-Switched Virtual Circuit is that an SVC must be reestablished each time data is to be sent. After that SVC disappears.

That depends on the operating system and computer architecture.
The amount of virtual terminals available is dependent on the switch itself. However, the average number is 15.
When there is a very current flow with virtual no voltage caused a hard wire short
.5 terabytes.
