Explanation
Layer 2 is the Data Link layer, responsible for node-to-node delivery using MAC (Media Access Control) addresses. Switches operate at Layer 2 by reading MAC addresses to intelligently forward frames only to the correct port. IP addresses operate at Layer 3 (Network), routers operate at Layer 3, and hubs operate at Layer 1 (Physical) - they simply repeat electrical signals without reading any addresses.
