Which of the following is true with respect to the data link layer?
A)It accepts streams of bits from the application layer.
B)It is responsible for encoding the bit-stream as a series of electronic voltages.
C)It performs error detection.
D)It performs routing functions.
E)It organizes data from the physical layer and passes these coherent messages directly to the application layer.

Question

Quizplus · Accepted Answer

The data link layer is responsible for framing the bits received from the physical layer and adding error detection information. It does not perform routing functions and does not organize data for the application layer. Encoding of the bit-stream into electronic voltages is done at the physical layer. Therefore, option A and B are incorrect.
