Identify the OSI layer in which MAC address is associated to _____________?PhysicalData LinkTransport Network

Step 1: Break Down the Problem

The question asks to identify the OSI layer associated with a MAC address from the given options: Physical, Data Link, Transport, and Network.

Step 2: Relevant Concepts

In the OSI (Open Systems Interconnection) model:

• Physical layer deals with the physical connection and transmission of raw data.
• Data Link layer is responsible for node-to-node data transfer and handling error correction from the physical layer. It includes protocols for MAC addressing.
• Transport layer manages end-to-end communication and data integrity.
• Network layer handles routing and forwarding of data packets.

Step 3: Analysis and Detail

The MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications at the Data Link layer. It operates directly beneath the Network layer and is vital for data packet transfer within local networks.

Step 4: Verify and Summarize

MAC addresses are primarily used for LAN data transfer, associating devices within the same local area. They are critical for identifying devices on the same network segment.

Final Answer

The MAC address is associated with the Data Link Layer of the OSI model.
