Which term describes a set of rules governing network communication?

The term that describes a set of rules governing network communication is "Protocols." Protocols are essential in networking as they dictate how data is transmitted, received, and interpreted across different devices and networks. They ensure that the various components of a network can communicate effectively by establishing common formats and rules for data exchange.

For example, protocols like TCP/IP (Transmission Control Protocol/Internet Protocol) outline how data packets are formatted, addressed, transmitted, and routed over a network. This standardization allows for seamless communication between devices produced by different manufacturers and is crucial for ensuring data integrity and accuracy during transmission.

In contrast, while "Nodes" refer to any active device that connects to a network and can send or receive data, they do not represent a set of rules. "Standards" relate to established norms or guidelines that may include protocols but are broader in scope and cover various aspects of technology. Lastly, "Configurations" refer to the settings and options applied to devices and systems within a network, which dictate how they operate rather than governing the foundational rules of communication itself. Thus, "Protocols" specifically encapsulates the essence of communication rules within a network.
