The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks.
TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination.
It is commonly known as TCP/IP, because its 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.
Layers
The Internet protocol suite 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
- The application layer, which provides process-to-process application data exchange
