 | | The de facto standard network protocol suite in use today is called TCP/IP, for Transmission Control Protocol/Internet Protocol. This protocol suite was developed by the Internet Engineering Task Force, and is the protocol suite used world-wide by hosts connected to the Internet. TCP/IP is also used for most UNIX-based local-area networking applications such as remote login and network file service. Another international standard protocol suite, usually called OSI (Open Systems Interconnect), has been standardized by the International Standards Organization (ISO). Although fairly popular in Europe, this protocol suite has never caught on in the United States, for a wide variety of both technical and political reasons. Although there was much talk of TCP/IP becoming obsolete when the ISO/OSI standards were first released, it is now clear that TCP/IP is here to stay, and even organizations that use ISO/OSI internally must also support TCP/IP if they want to connect to the outside world and the Internet. | |
