In telecommunications, a communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. These are the rules or standard that defines the syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both.
Communicating systems use well-defined formats (protocol) for exchanging messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. [2]
Introduction[edit]
Network protocols[edit]
This video is very technical, but one of the best I could find about network protocols. It may be helpful to review the OSI model prior to watching this.
Explain the importance of protocols and standards on the web.[edit]
Without protocols and standards we wouldn't be able to achieve interoperability. That is, if my website used a totally different protocol for storing data (non-html) your browser would not be able to parse it, and you as a user wouldn't be able to understand it.
