Detailed explanation-1: -The Ethernet broadcast address is distinguished by having all of its bits set to 1. As such, its MAC address is the hexadecimal value of FF:FF:FF:FF:FF:FF. This address is used to transmit data to all of the hosts on the local subnet.
Detailed explanation-2: -There are two primary addresses assigned to a device on an Ethernet LAN: Physical address (the MAC address) – Used for Ethernet NIC to Ethernet NIC communications on the same network. Layer 2 or physical addresses, like Ethernet MAC addresses, have a different purpose.
Detailed explanation-3: -The LLC sublayer is responsible for communicating with the upper layers, and the MAC sublayer communicates directly with the physical layer.
Detailed explanation-4: -The MAC sublayer is the lower of the two data link sublayers and is closest to the physical layer. The two primary functions of the MAC sublayer are to encapsulate the data from the upper layer protocols and to control access to the media.
