TCP/IP, which was developed in 1969 by the U.S. Department of Defense (DoD) Advanced Research Projects Agency (DARPA), is the result of a resource-sharing experiment called Advanced Research Projects Agency Network (ARPANET). The TCP/IP protocol was developed to provide high-speed communication network links. Since 1969, ARPANET has grown into a worldwide community of networks known as the Internet. Before TCP/IP, there was no way for computers to communicate easily and securely on public networks.
The TCP/IP Protocol Suite. The TCP/IP protocol suite maps to a four-layer conceptual model known as the DARPA model, which was named after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet, and Network Interface.
