Answer 1

This question is about different layers of abstraction in computer networks and their descriptions.

Step-by-step explanation:

1. Physical Layer: Responsible for the physical transmission of data.
2. Data Link Layer: Responsible for error detection and correction at the data link level.
3. Network Layer: Responsible for routing packets across multiple networks.
4. Transport Layer: Responsible for breaking data into smaller units and reassembling them at the receiving end.
5. Session Layer: Responsible for establishing, managing, and terminating sessions between applications.
6. Presentation Layer: Responsible for converting data into a format that can be understood by the receiving application.
7. Application Layer: Responsible for providing services to the user applications.
