What are two services performed by the data link layer of the OSI model? (Choose two.)
Answer: The data link layer work to exchange the frames between nodes on a physical media. The basic work of the data link layer is:
The path is determined by layer 3, while layer 2 is responsible to develop the MAC address table which is its work.
Datalink layer work is to manage the data movements in and out of the physical link over a network. In the OSI model, it is referred to as the Open System Interconnection (OSI). The bits encoding and decoding happen in the data link layer right before they need to move in the form of the frames between nodes. It can also check the method the device recovery after collision (a process where all the nodes send the frames at a time). The data link and two more layers one is LLC (logical link layer) and the other one is MAC (Media access layer).
LLC work is to handle the data flow of the different applications and the error detection, acknowledgement is also a function of it.MAC layer can handle access to the physical media. The physical addressing of the packets is also the work of the MAC layer. Ethernet and 802.11 wireless are common examples of it. the function of the data link layer are :
