At what layer in the OSI model are hardware addresses referenced?
Hardware addresses, commonly referred to as MAC (Media Access Control) addresses, are used at the Data Link layer of the OSI model. This layer is responsible for node-to-node data transfer and physical addressing. Devices such as switches operate at this layer to forward data based on MAC addresses.
hardware addresses is the MAC addresses so it would go in the 2 layer where it would be use by switches
