What describes a set of rules governing the exchange or transmission of data between devices?

• A. IP Address
• B. Bandwidth
• C. Protocol
• D. Syntax

Answer: (C)

A protocol is the set of rules that governs how data is exchanged between devices. It specifies how messages are formatted, the order in which they are sent and received, how connections are established and terminated, and how errors are detected and handled so both sides can understand each other. Examples like HTTP define how web requests and responses look, while TCP ensures data is delivered reliably. In contrast, an IP address identifies a device on the network, bandwidth refers to the capacity to move data, and syntax describes the structure of a language or data format but not the overarching rules for exchanging data.
