Overview#Internet Protocol Suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks.
Internet Protocol Suiteis 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 during its development.
Internet Protocol Suite is occasionally known as the United States Department of Defense (DoD) model, because the development of the networking model was funded by DARPA, a United States Federal Agency of the United States Department of Defense.
TCP/IP provides end-to-end payload communication specifying how data should be packetized, addressed, transmitted, routed and received. This functionality is organized into four abstraction Communication 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 methods for data that remains within a single network segment (link)
- Internet Layer - connecting independent networks, thus providing internetworking - Internet Protocol (IP)
- Transport Layer - handling host-to-host communication and includes:
- Application Layer - which provides process-to-process data exchange for applications.
