Which layer of the OSI model ensures error detection and correction?

Which layer of the OSI model ensures error detection and correction?

Step 1: Understand the OSI model, which has 7 layers that help in networking.
Step 2: Identify the layers of the OSI model: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Step 3: Focus on the Data Link Layer, which is the second layer of the OSI model.
Step 4: Learn that the Data Link Layer is responsible for ensuring reliable communication between devices on the same network.
Step 5: Recognize that error detection and correction are important for maintaining data integrity.
Step 6: Know that the Data Link Layer uses methods like checksums and Cyclic Redundancy Check (CRC) to detect and correct errors.
