The internet model consists of ..................layers.
The internet model consists of Five layers.
The 5-Layer Model (the TCP Model) The 5-layer model serves primarily the protocols known as Transmission Control Protocol (TCP) and Internet Protocol (IP), or jointly, TCP/IP. ... The 5-layer model was developed along with these protocols, antedating the 7-layer model, and is sometimes called the TCP Model.
In some sites , It is given that tcp/ip has 4 layers,network access,internet,transport,application. But in some other references , it is given that it has 5 layers (instead of network access, physical and link).
TCP/IP protocols map to a four-layer conceptual model known as the DARPA model , named after the U.S. government agency that initially developed TCP/IP. The four layers of the DARPA model are: Application, Transport, Internet, and Network Interface.
In the seven-layer OSI model of computer networking, the session layer is layer 5. The session layer provides the mechanism for opening, closing and managing a session between end-user application processes, i.e., a semi-permanent dialogue.
