What are the responsibilities of data link layer Mcq?

Data-link layer: This layer is responsible for moving frames from one hop to next. The Data-link layer divides the stream of bits received from the network layer into manageable units called frames. It adds a header to the frame to define the sender and receiver of the frame.

What are the five duties of data link layer?

The main functions of data link layer include framing, error detection and correction, acknowledgement, flow control, ensuring well-defined reliable service interface to the network layer, encapsulating packets from network layer to frames, etc.

Is data link layer responsible for flow control?

Layer 2: Data Link The data link layer is divided into two sublayers: Logical Link Control (LLC) sublayer provides the logic for the data link. Thus, it controls the synchronization, flow control, and error checking functions of the data link layer.

Is data link layer responsible for framing?

Framing is a function of the data link layer. It provides a way for a sender to transmit a set of bits that are meaningful to the receiver.

Which of the following is not responsibility of data link layer?

2. Which of the following tasks is not done by data link layer? Explanation: Channel coding is the function of physical layer. Data link layer mainly deals with framing, error control and flow control.

What are the functions of the data link MAC layer Mcq?

pathway for multiplexing of data streams, data frame detection, B. medium access control (mac) and error control.

Which of the layer is responsible for error and flow control?

Logical Link Control (LLC) sublayer
The Logical Link Control (LLC) sublayer is responsible for flow controls and error controls that ensure error-free and accurate data transmission between the network nodes.

Which layer is responsible for error control and flow control?

Data-link layer is responsible for implementation of point-to-point flow and error control mechanism.

Which layer is responsible for the encoding of signals?

The data link layer is also called as the Layer 2 of the OSI model. Here are the basic functionalities of the data link layer: Responsible for encoding and decoding of the electrical signals into bits.

What is one main characteristic of the data link layer?

A: It shields the upper layer protocol from being aware of the physical medium to be used in the communication.
