Abstract

The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP IP, because it's most important protocols, the Transmission Control Protocol TCP and the Internet Protocol IP , were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense. TCP IP provides end to end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved. From lowest to highest, the layers are the link layer, containing communication technologies for a single network segment link the internet layer, connecting hosts across independent networks, thus establishing internetworking the transport layer handling host to host communication and the application layer, which provides process to process application data exchange. Our aim is describe operation and models of TCP IP suite in data communication networking.
