Which OSI layer is associated with WLAN data framing and MAC addressing?

• A. The Data Link Layer
• B. The Network Layer
• C. The Physical Layer
• D. The Transport Layer

Answer: (A)

Framing and MAC addressing are responsibilities of the Data Link layer. This layer wraps network-layer packets into frames suitable for a local link and uses MAC addresses to identify devices on that link. In WLANs (802.11), the MAC sublayer defines how frames are formed, addressed, and how access to the wireless medium is coordinated using MAC addresses. The Network layer handles IP addressing and routing, the Physical layer handles the actual transmission of bits, and the Transport layer deals with end-to-end delivery features. So, the Data Link Layer is the part of the OSI model associated with WLAN data framing and MAC addressing.
