The Data Link Layer in the OSI model is responsible for ensuring error-free data transmission between nodes on the same network segment. It manages data frames, error detection, and flow control to ensure reliable communication between devices. This layer ensures that data is delivered without errors or duplications within a local network.

Data Link Layer

The Data Link Layer is responsible for ensuring error-free data transmission and managing data frames between nodes in a network. Here's how it achieves these functions:

- Error-free data transmission: The Data Link Layer uses techniques like error detection and correction to ensure that data is transmitted accurately between nodes. It checks for errors in the data received and requests retransmission if any errors are detected.

- Managing data frames: The Data Link Layer breaks down data from the network layer into frames for transmission and reassembles them at the receiving end. It adds necessary headers and trailers to the frames for addressing and error detection.

Overall, the Data Link Layer plays a crucial role in the reliable transmission of data within a network by handling error detection and correction mechanisms and managing the flow of data frames between nodes.
