Explanation

Layer 2 switches use MAC (Media Access Control) addresses to direct packet transmission to the intended recipient. MAC addresses are hardware addresses associated with network interface cards (NICs) and are unique identifiers at the data link layer (Layer 2) of the OSI model. Switches use MAC address tables to forward Ethernet frames only to the port where the destination MAC address is located, improving network efficiency by reducing unnecessary traffic on the network.
