Which layer of the OSI Model is responsible for data link protocols?

Layer 2 of the OSI Model is specifically designed for data link protocols. This layer is crucial because it provides node-to-node data transfer and handles error correction from the physical layer. It facilitates the reliable transmission of data frames between two directly connected nodes and ensures that data can be transmitted without errors and in the correct sequence.

Additionally, Layer 2 is responsible for managing how devices on a network gain access to data and permission to transmit it. It includes protocols like Ethernet and PPP (Point-to-Point Protocol) that define how packets are framed and addressed.

The importance of Layer 2 becomes evident in network operations, as it influences how frames are sent and received on the local network segment, directly impacting both network speed and reliability.
