What type of devices utilize MAC addresses for identification?

MAC (Media Access Control) addresses are unique identifiers assigned to network interfaces for communications on the physical network segment. These addresses play a crucial role in distinguishing devices on a local network.

All networked devices, including but not limited to computers, printers, switches, routers, and wireless access points, use MAC addresses to facilitate communication. The MAC address enables devices on the same LAN (Local Area Network) to identify and communicate with each other effectively at the data link layer of the OSI (Open Systems Interconnection) model.

While computers, routers, switches, and wireless access points certainly utilize MAC addresses, the statement that all networked devices, including printers, is the most comprehensive. Printers connected to a network have MAC addresses assigned to their network interface so that other devices can communicate with them without confusion, further emphasizing the universal application of MAC addresses across all device types in a networked environment.
