Which addresses are used in data link layer?
Media Access Control (MAC) Address – MAC address is used by the Media Access Control (MAC) sublayer of the Data-Link Layer. MAC Address is worldwide unique since millions of network devices exist and we need to uniquely identify each.
Where is the data link?
The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer.
What is the purpose of a data link?
A data link is a method for connecting one location to another in telecommunications, in order to transmit and receive digital information. Data transfer happens over a certain link protocol that allows data to be transferred from the source to the destination.
What is LLC and MAC?

What does link mean in network?
In a telecommunications network, a link is a communication channel that connects two or more devices for the purpose of data transmission. The link may be a dedicated physical link or a virtual circuit that uses one or more physical links or shares a physical link with other telecommunications links.
What is network layer address?
The Network Layer protocol translates logical addresses to MAC addresses. For example, if you use IP as the Network Layer protocol, devices on the network are assigned IP addresses, such as 207.120.67.30.
What is LLC in data link layer?
The logical link control (LLC) is the upper sublayer of the data link layer of the open system interconnections (OSI) reference model for data transmission. It acts act an interface between the network layer and the medium access control (MAC) sublayer of the data link layer.
What is the difference between a MAC address and an LLC Address explain?
Difference between MAC and LLC: The MAC layer is used for defining the working or functionality of which is unique for a particular network technology like Ethernet. The LLC layer is used for adding a field to each Ethernet frame.
