Broadcasts are useful for resolving MAC addresses as they allow the device to query the entire network for the location of a specific MAC address. However, this process can eat up bandwidth as every device on the network receives the broadcast message, even if they are not the intended recipient. Switches and routers can also assist with MAC address resolution, but they do not have the same level of efficiency as broadcasts for this specific task. Unicasts are not useful for resolving MAC addresses as they only send messages to a specific device, rather than querying the entire network.
