Gartner Glossary

Protocol

A set of procedures in telecommunications connections that the terminals or nodes use to send signals back and forth. Transmission Control Protocol/Internet Protocol (TCP/IP) is the standard protocol for the Internet and related networks such as intranets and extranets. Local-area networks (LANs) often rely on a different protocol. Networks and systems cannot communicate unless they use the same protocol or make use of a gateway.
