A _____ set of rules which that governs data communicationa.RFCsb.Protocolsc.Standardsd.Servers

The correct answer to the question is:

b. Protocols

Explanation:

In the context of data communication, a protocol is a set of established rules that dictate how data is transmitted and received over a network. Protocols ensure that devices from different manufacturers can communicate effectively by standardizing the techniques and processes used in data exchange. This includes defining message formats, error handling, data compression, and acknowledgments for data transmission, among other functions.

Other options provided do not fit the definition as closely:

• RFCs (Request for Comments) are a series of memoranda describing methods, behaviors, investigations, or advances related to the operation of the Internet and Internet-connected systems but are not specifically a set of rules themselves.
• Standards can refer to broader guidelines, including but not limited to protocols, which are more specific.
• Servers refer to hardware or software that provides functionality for other programs or devices, known as clients, but do not represent a set of rules for communication.

Thus, protocols are the most accurate term to fill in the blank.
