A Protocol is the set of rules, syntax, semantics and synchronization of communication and even the possible error recovery methods that allow two or more entities in a system to transmit information.

Network protocols comprise mechanisms for devices to recognise and make connections with each other, and as formatting rules, which specify how data is packed into messages sent and received.
