Question

Quizplus · Accepted Answer

A protocol is a set of rules and procedures that dictate how devices communicate in a network. It defines the format of messages, the order in which they are sent and received, and how errors are handled. Examples of network protocols include TCP/IP, HTTP, and FTP.

Option A is incorrect because a device that handles the switching of voice and data in a local area network is called a switch, not a protocol.

Option C is incorrect because a communication service for microcomputer users is usually referred to as a terminal service, not a protocol.

Option D is incorrect because the main computer in a telecommunications network is called a server, not a protocol.

Option E is partially correct, but it only describes the function of a routing path, not a protocol. A protocol is the set of rules that determine how packets are routed through the network, but the routing path itself is simply a physical or logical path that packets follow.
