protocol

Statistics

The step-by-step procedure for carrying out an experimental design.

Computer

An agreement that governs the procedures used to exchange information between cooperating entities. More specifically, a protocol is such an agreement operating between entities that have no direct means of exchanging information, but that do so by passing information across a local interface to so-called lower-level protocols, until the lowest, physical, level is reached. The information is transferred to the remote location using the lowest-level protocol, and then passes upward via the interfaces until it reaches the corresponding level at the destination. In general, a protocol will govern the format of messages, the generation of checking information, and the flow control, as well as actions to be taken in the event of errors.
A set of protocols, governing the exchange of information between (physically remote) communicating entities at a given level, and the set of interfaces governing the exchange between (physically adjacent) protocol levels, are collectively referred to as protocol hierarchy or a protocol stack.
See also seven-layer reference model.

Internet

A set of rules and a vocabulary that define how two entities in a network communicate with each other.

Electronics and Electrical Engineering

In the transfer of digital signals across a switched system, the structure to which a digital message must conform if it is to be acceptable to the switching network: the message must be able to be identified as a valid message and must have a sender and recipient identifier. A typical example would be where the message has a header block of digits giving information about the sender and the recipient and possibly the length of the message. It will also have a terminating block of digits that indicate the end of the message and, optionally, further information to verify the accuracy of the message.
