# Protocol
A protocol is a set of rules that defines how data is formatted, transmitted, and received between devices on a network. Protocols ensure that different systems, regardless of manufacturer or operating system, can predictably communicate with each other. Examples include TCP, IP, HTTP, and DNS, each governing a specific aspect of how network communication works.
