In Frame Relay, what does the term 'PVC' stand for?

Permanent Virtual Channel
Public Virtual Circuit
Private Virtual Connection
Point-to-Point Virtual Circuit

The correct answer is: Permanent Virtual Channel

The term 'PVC' in Frame Relay stands for "Permanent Virtual Circuit." This concept refers to a virtual circuit that is established between two endpoints and remains in place for an extended period, enabling consistent and reliable communication. Unlike switched virtual circuits, which are created and torn down on demand, a PVC is a dedicated path that offers predictable performance and is always available for data transfer, making it ideal for applications requiring constant connectivity. While the other terms may sound plausible in the context of networking, they do not accurately represent the established terminology associated with Frame Relay technology. The notion of a "permanent" connection highlights the ongoing nature of this type of virtual circuit, distinguishing it from alternatives that may imply variability or temporary states. Understanding this foundational concept is crucial for working effectively with Frame Relay networks.
