Protocols and standards on the web
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]

What do you actually NEED to know?[edit]
There are certain standards you must know in order to complete IB diploma. These are not fully complete, in my opinion, but they are here for your reference:
