Which term describes the logical (virtual) connection points associated with a communication protocol to facilitate communications across networks?

• A. Protocol
• B. Port
• C. Private Network
• D. PVV

Answer: (B)

The idea being tested is that communications use logical endpoints called ports. In TCP/IP, every communication to a host combines an IP address with a port number to direct the data to the correct service. The port acts as a virtual doorway for a specific application (for example, port 80 for HTTP or port 443 for HTTPS). These ports are not physical connectors; they’re logical identifiers that the transport protocol uses to route data to the right process across the network. That’s why this term best fits “the logical (virtual) connection points associated with a communication protocol to facilitate communications across networks.”

A protocol describes the rules for how data is exchanged, not where it’s delivered. A private network refers to network segmentation or isolation, not the endpoints for communications. PVV isn’t a standard networking term.
