Computers communicating on a network must follow a _____, a common set of rules for exchanging information.

• A. Syntax
• B. Model
• C. Standard
• D. Protocol

Answer: (D)

Computers communicating on a network must follow a protocol, a defined set of rules for exchanging information. A protocol covers how data is formatted, how messages are timed and ordered, how devices address one another, and how errors are detected and handled. This ensures different devices and software can understand each other and work together. Syntax is only about the structure of the data, not the overall rules for exchanging it. A model is an abstract framework describing layers and interactions, not the actual rule set used on the network. A standard is a general guideline or requirement, whereas a protocol is the concrete set of rules that governs the communication itself.
