What are the functions of data link layer in OSI model?
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.
What is data link control layer?
DLC (data link control) is the service provided by the Data Link layer of function defined in the Open Systems Interconnection (OSI) model for network communication. The Data Link layer is responsible for providing reliable data transfer across one physical link (or telecommunications path) within the network.

What is link layer addressing?
A link-layer address is called a link address, called a physical address, and sometimes a MAC address. Since a link is controlled at the data-link layer, the addresses need to belong to the data-link layer. These two addresses are changed every time the frame moves from one link to another.
What is the significance of data link layer explain the design issues of data link layer?
The data link layer in the OSI (Open System Interconnections) Model, is in between the physical layer and the network layer. This layer converts the raw transmission facility provided by the physical layer to a reliable and error-free link.
What is data link protocols?
In networking and communications, the transmission of a unit of data (frame, packet) from one node to another. Known as a “layer 2 protocol,” the data link protocol is responsible for ensuring that the bits and bytes received are identical to the bits and bytes sent.
What are the data link layer issues?
It is the second sub-layer of data-link layer. It controls the flow and multiplexing for transmission medium. Transmission of data packets is controlled by this layer. This layer is responsible for sending the data over the network interface card.
