Faculty: Mohammed A.Salam Semester: Summer 1 Class : CCNA

Protocols Protocols are the rules to communicate between two computers on the network. In [|computing] and [|telecommunications], a **protocol** or **communications protocol** is a formal description of message formats and the rules for exchanging those messages. Protocols may include [|signaling], [|authentication] and [|error detection and correction] capabilities. In its simplest form, a protocol can be defined as the rules governing the [|syntax], [|semantics], and synchronization of communication. Protocols may be implemented by hardware, software, or a combination of the two. At the lowest level, a protocol defines the behaviour of a hardware connection.
