Which term describes the rules for transmitting data over networks such as the web?

• A. Standards
• B. Protocols
• C. Languages
• D. Models

Answer: (B)

Protocols describe the rules for transmitting data over networks. They define how messages are formatted, the sequence of actions devices follow to send and receive, how reliability and order are ensured, and how errors are detected and handled. For the web, a prime example is HTTP, which specifies how a client requests a resource and how the server responds. HTTP sits on top of other protocols like TCP for reliable delivery and IP for routing, showing how the different layers work together to move information across the network. Standards can formalize specifications that may include protocols, but the specific rules governing communication are what protocols provide. Languages pertain to programming or data representation, not the rules of data exchange, and models are abstract frameworks used to organize or describe how networks operate rather than the transmission rules themselves.
