What is the use of LLC layer in Ethernet?

The LLC (Logical Link Control) layer in Ethernet serves as a bridge between the data link layer and the network layer, providing an interface for multiple network protocols to operate over the same physical network. It is responsible for framing, addressing, and managing the flow of data, ensuring reliable communication between devices. By offering features like error detection and control, the LLC layer enhances the overall efficiency and reliability of data transmission in Ethernet networks.
