The network access layer, Internet layer, transport layer, application layer. Due to the wide variety of solutions for the physical network structure that existed at the time of development, TCP / IP model provides an interface to the network access layer by treating it as a monolith. This layer corresponds to the two lowest layers, the physical and data link ISO / OSI model. Internet layer corresponds to the network layer in the full range of functionality. Transport Layer TCP / IP model implements the same functions as the transport layer ISO / OSI model, and in addition deals with fundamental aspects related to the management of sessions applicative. Other tasks of the session layer ISO / OSI model and presentation layer functions and applications have been placed in the TCP / IP model application layer. Currently, family TCP / IP is the basic model of Internet communication and the vast majority of local area networks to the Internet are not disks.
