Show Hint
The data link layer is crucial for reliable communication between devices, focusing on data integrity and flow control. It does not handle routing, which is the responsibility of the network layer.

The Correct Option is C
Solution and Explanation
The **data link layer** is responsible for node-to-node data transfer and error checking, ensuring reliable communication between devices. Its key functions include: - **A. Providing a well-defined interface to the network layer**: The data link layer provides a clear and defined method for the network layer to send and receive data packets. This ensures that data is passed from the network layer to the physical layer correctly. - **B. Dealing with transmission errors**: One of the essential functions of the data link layer is to detect and correct errors that occur during transmission. This is achieved through mechanisms like checksums and CRC (Cyclic Redundancy Check). - **C. Regulating the flow of data so that slow receivers are not swamped by fast senders**: The data link layer controls data flow by using techniques like flow control, which helps prevent overwhelming slower receivers. - **D. Routing packets from the source machine to the destination machine**: This is not a function of the data link layer. Routing packets is performed by the **network layer** (Layer 3) in the OSI model. Step 2: Conclusion.
The data link layer handles functions related to data transmission and error correction but does not handle routing. Therefore, the correct answer is **(3) A, B, and C only**.

Top Questions on Data Link Layer
Consider the sliding window flow-control protocol operating between a sender and a receiver over a full-duplex error-free link. Assume the following:
- The time taken for processing the data frame by the receiver is negligible.
- The time taken for processing the acknowledgement frame by the sender is negligible.
- The sender has infinite number of frames available for transmission.
- The size of the data frame is 2,000 bits and the size of the acknowledgement frame is 10 bits.
- The link data rate in each direction is 1 Mbps (= 106 bits per second).
- One way propagation delay of the link is 100 milliseconds.
The minimum value of the sender’s window size in terms of the number of frames (rounded to the nearest integer) needed to achieve a link utilization of 50% is .

- Consider the cyclic redundancy check (CRC) based error detecting scheme having the generator polynomial $X^3 + X + 1$. Suppose the message $m_4 m_3 m_2 m_1 m_0 = 11000$ is to be transmitted. Check bits $c_2 c_1 c_0$ are appended at the end of the message by the transmitter using the above CRC scheme. The transmitted bit string is denoted by $m_4 m_3 m_2 m_1 m_0 c_2 c_1 c_0$. The value of the checkbit sequence $c_2 c_1 c_0$ is
