What is Internet Protocol Suite
The Internet protocol suite, according to WikipediA, is the conceptual model and set of communications protocols used in the Internet and similar computer networks. It is commonly known as TCP/IP because the foundational protocols in the suite are the Transmission Control Protocol (TCP) and the Internet Protocol (IP). It is occasionally known as the Department of Defense (DoD) model because the development of the networking method was funded by the United States Department of Defense through DARPA.
The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to the scope of networking involved. From lowest to highest, the layers are the link layer, containing communication methods for data that remains within a single network segment (link); the internet layer, providing internetworking between independent networks; the transport layer, handling host-to-host communication; and the application layer, providing process-to-process data exchange for applications.
The technical standards underlying the Internet protocol suite and its constituent protocols are maintained by the Internet Engineering Task Force (IETF). The Internet protocol suite predates the OSI model, a more comprehensive reference framework for general networking systems.
Internet Protocol suite (IP suite), according towhatis.techtarget.com, is the standard network model and communication protocol stack used on the Internet and on most other computer networks. While other networking models exist, the IP suite is overwhelmingly the global standard for computer-to-computer communication.
The IP suite follows a client/server model, in which multiple client programs share the services of a common server program. Protocols in the suite define end-to-end data handling methods for everything from packetizing, addressing and routing to receiving. Broken down into layers the IPS includes the link layer, the internet layer, the transport layer, application layer and the physical layer. Each layer contains a number of protocols for communications. The suite is sometimes just called TCP/IP, because those are the predominant protocols in the model and were the first ones used. However, the IP suite involves many other protocols.
