Data Link Layer
The Data Link Layer is the second layer in the OSI model, responsible for providing node-to-node data transfer and handling error correction from the physical layer. The Data Link Layer encapsulates packets from the Network Layer into frames, adds necessary headers and trailers, and ensures that data is transmitted efficiently and without errors across physical networks. It is crucial for both wired and wireless networking and plays a vital role in providing a reliable communication link between physical network nodes.
