What is a protocol?

Explanation:
Protocols are the defined rules that govern data transmission, including how data is formatted, the sequence of messages, timing, and how errors are handled. This shared understanding lets different devices and software from various vendors communicate reliably. The statement that specifies the format of data and the rules during transmission captures this idea most completely. The other concepts describe hardware connections, synchronization standards, or configuration tools, which are not themselves the rules that govern communication.
