Show answer & explanation
Correct answer: D
The OSI model includes seven layers, while the TCP/IP model has four. The Presentation and Session layers in the OSI model are not explicitly defined in the TCP/IP model. In TCP/IP, the functions of these layers are handled by the application layer or transport layer. This makes the Presentation and Session layers additions in the OSI model compared to TCP/IP.
