Questions & Step-by-Step Solutions
Which layer of the OSI model does the MAC address operate at?
Step 1: Understand what the OSI model is. It is a framework that describes how different networking protocols interact in seven layers.
Step 2: Identify the layers of the OSI model. They are: 1) Physical, 2) Data Link, 3) Network, 4) Transport, 5) Session, 6) Presentation, 7) Application.
Step 3: Learn about MAC addresses. A MAC (Media Access Control) address is a unique identifier assigned to network interfaces for communications on the physical network segment.
Step 4: Determine where the MAC address fits in the OSI model. The MAC address is used for data transfer between devices on the same local network.
Step 5: Conclude that since the MAC address is used for node-to-node communication, it operates at the Data Link Layer.
