Answer to Question 1

D

Answer to Question 2

This layer takes unpackaged bit stream data arriving from the physical layer and packages the bits into units called frames. The data link layer attaches a physical address to each frame. This layer is responsible for getting each frame from one node to another on its way from sender to receiver. This layer also provides for flow control, error control, and access control. So, whereas the network layer provides for logical addressing, the data link layer provides for physical addressing.
