Which layer corresponds to 'presentation' in the described layer scheme?

• A. 6 - Presentation
• B. 7 - Application
• C. 5 - Session
• D. 3 - Network

Answer: (A)

The important idea is how the OSI layers are numbered and what each layer does. In the OSI model, the presentation layer is the sixth layer. It handles data formatting, encoding/decoding, encryption, and compression—basically making sure the data from the application layer is properly represented for transport and interpretation by the other layers. Given the scheme lists 6 - Presentation, 7 - Application, 5 - Session, and 3 - Network, the entry that matches the presentation role is the one that states 6 - Presentation. The other options point to the application (7), session (5), and network (3) layers, which are not responsible for data presentation.
