Which OSI layer handles frames and MAC addressing, typically with switches?

Explanation:
Frames and MAC addressing sit at the Data Link layer. This layer is responsible for node-to-node data transfer on a local link and for framing data into units called frames. The MAC sublayer handles hardware addressing using MAC addresses and governs access to the physical medium. Switches operate primarily at this layer, using MAC addresses learned in a CAM table to forward frames to the correct port. The Physical layer below it carries the raw bits, the Network layer above it handles logical addressing and routing, and the Transport layer manages end-to-end delivery and reliability.
