!!! Overview
[{$pagename}] is the computer networking model and set of communications [protocols] used on the [Internet] and similar computer [networks]. 

[{$pagename}]is commonly known as [TCP/IP|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. 

[{$pagename}] 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|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:
** [Transmission Control Protocol] ([TCP])
** [User Datagram Protocol] ([UDP])
* [Application Layer] - which provides process-to-process data exchange for [applications].
