Explanation

MAC (Media Access Control) addresses are Layer 2 (Data Link) addresses. They are hardcoded into network interface cards (NICs) and used to identify devices on a local network segment. The Data Link layer is responsible for node-to-node delivery using these physical hardware addresses. Layer 3 (Network) uses IP addresses for logical addressing. Layer 1 (Physical) deals with raw bit transmission over media. Layer 4 (Transport) uses ports and manages end-to-end communication.
