protocol

A set of formal rules describing how to transmit data, especially across a network. Low level protocols define the electrical and physical standards to be observed, bit- and byte-ordering and the transmission and error detection and correction of the bit stream. High level protocols deal with the data formatting, including the syntax of messages, the terminal to computer dialogue, character sets, sequencing of messages etc.

Many protocols are defined by RFCs or by OSI.

protocol

The format of data and the procedure that manages the exchange of the data between two locations. The term protocol is commonly used with networks and communications. However, a protocol may refer to an exchange of data between applications within a computer, although that process is more likely called an application programming interface (see API). The term comes from the Greek "protokollon," which was the cover page to a manuscript that provided a description of the contents. See communications protocol, protocol stack, blockchain protocol and OSI model.

Protocol

 

a body of generally accepted rules, traditions, and conventions observed by governments, departments of foreign affairs, diplomatic representatives and employees, and other officials in international relations.

Protocol determines the order of visits, the forms of diplomatic correspondence, and the procedure for diplomatic receptions. It regulates the manner of receiving a foreign head of state, the head of government of a foreign state, and other foreign dignitaries and governmental delegations. All countries adhere to the rules of protocol, although each country applies them with due regard for its social structure, national characteristics, and customs.
