protocol (redirected from protocolar)

protocol (prō`təkŏl), term referring to rules governing diplomatic conduct or to a variety of written instruments. Examples of the latter are authenticated minutes of international conferences; preliminary agreements, or statements of principle, which eventuate in a formal treaty; and agreements that do not require ratification. Sometimes the term protocol is applied to an agreement that in all essentials of form or content is similar to a treaty; an example of this was the Geneva Protocol approved by the Assembly of the League of Nations in 1924, which branded aggressive war an international crime. It provided that no signatory would engage in war with other signatories who observed their international obligations. Signatories were to participate in an international disarmament conference. The protocol was supported by most nations, but British refusal to support it in the League Council prevented it from coming into force. The Locarno Pact and the Kellogg-Briand Pact were later agreements having the general tenor of the Geneva Protocol. Diplomatic protocol is the code of international courtesy governing the conduct of those in the diplomatic service or otherwise engaged in international relations. It is basically concerned with procedural matters and precedence among diplomats. Each office of foreign affairs (or equivalent body) has an official in charge of protocol.

protocol

In computer science, a set of rules or procedures for transmitting data between electronic devices, such as computers. In order for computers to exchange information, there must be a preexisting agreement as to how the information will be structured and how each side will send and receive it. Without a protocol, a transmitting computer, for example, could be sending its data in 8-bit packets while the receiving computer might expect the data in 16-bit packets. Protocols are established by international or industrywide organizations. Perhaps the most important computer protocol is OSI (Open Systems Interconnection), a set of guidelines for implementing networking communications between computers. The most important sets of Internet protocols are TCP/IP, HTTP, and FTP.

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.
