This protocol suite is usually referred to as TCP/IP partly because TCP and IP are two of the most important protocols of the collection. TCP/IP includes a set of standards that specify how networked computers communicate and how data is routed through the interconnected computers. TCP/IP provides the application programmer with two primary services: connectionless packet delivery and reliable stream transport.
