Chapter Summary Continued
TCP/IP maps to a four-layer network model.
The layers are Application, Transport, Internetwork, and Network Interface.
These layers map to equivalent functions in the OSI model.
The Application layer in the TCP/IP model covers the Application, Presentation, and Session layers of the OSI model.
The TCP/IP Transport layer maps directly to the OSI Transport layer.
The Internetwork Layer of the TCP/IP model maps directly to the Network Layer of the OSI model.
The Network Interface Layer of the TCP/IP model is equivalent to the Data Link and Physical Layers of the OSI model.
