A set of rules that governs data communication:

  • A.Protocols
  • B.Standards
  • C.RFCs
  • D.None of the mentioned

Answer: A

Correct answer: Protocols

A protocol is the agreed set of rules governing a data exchange, covering syntax, semantics and timing. Standards are the documents that record such agreements formally and give them authority, and RFCs are the particular series in which the IETF publishes them. The rules themselves are the protocol; the standard and the RFC are how the rules are written down and disseminated.
