Which three layers of the OSI model are comparable in function to the application layer of the TCP/IP model? (Choose three.)

Answer

The TCP/IP model is a simpler model compared to the OSI model, and its Application layer encompasses several functions that in the OSI model are divided among three layers. The three layers of the OSI model that are comparable in function to the Application layer of the TCP/IP model are:

1. Application Layer (OSI): This layer directly interacts with user applications and provides services such as email, file transfer, and web browsing.

2. Presentation Layer (OSI): This layer is responsible for data translation, encryption, and compression. It formats and presents data for the application layer, making sure data is in a usable form.

3. Session Layer (OSI): This layer manages sessions, or connections, between applications. It establishes, maintains, and terminates communication sessions between applications.

These three layers combined provide the functionalities that the Application layer of the TCP/IP model encapsulates, thus making them comparable in function.
