Wes Bryan Sir in WAN Technologies Part 2 of CompTIA Network + mentioned that a Permanent Virtual Circuit is established during Frame Relay. I didn't get the Virtual thingy here. Can someone please explain that part?
Doubt in Frame Relay
Remember that a "Virtual" anything is a logical or software-based. So a virtual virtual is made up of two data terminal endpoints and a path through the Frame Relay mesh network. This is not a dedicated or static path as the underlying connections in the mesh network are abstracted from the customer.
