Which term is an agreed-upon method of communication used within networks, describing rules and procedures that devices should follow?

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

Answer: (D)

The term that fits describes the agreed-upon method of communication used within networks, outlining the rules and procedures devices should follow. This is what a protocol is: a standard set of rules that governs data formats, sequencing, addressing, error handling, and how sessions start and end. Protocols enable different devices and systems to communicate reliably and interoperably, even if they come from different vendors. Examples include TCP/IP for network communication, HTTP for web transfers, and DNS for name resolution.

PVV isn’t a standard networking term for communication rules. A private network refers to a network’s scope or accessibility, not the formal rules devices must follow. PTS isn’t the established term used to describe the rules and procedures governing network communication.
