TCP/IP Protocol Suite

  • Article

TCP/IP is an industry-standard suite of protocols designed for large internetworks spanning wide area network (WAN) links. TCP/IP was developed in 1969 by the U.S. Department of Defense Advanced Research Projects Agency (DARPA), the result of a resource-sharing experiment called ARPANET (Advanced Research Projects Agency Network). The purpose of TCP/IP was to provide high-speed communication network links. Since 1969, ARPANET has grown into a worldwide community of networks known as the Internet.
