Detailed explanation-1: -A unicast MAC address is the unique address used when a frame is sent from a single transmitting device to a single destination device. A broadcast packet contains a destination IPv4 address that has all ones (1s) in the host portion.
Detailed explanation-2: -Each MAC address is unique to the network card installed on a device, but the number of device-identifying bits is limited, which means manufacturers do reuse them.
Detailed explanation-3: -The MAC address is a unique value associated with a network adapter. MAC addresses are also known as hardware addresses or physical addresses. They uniquely identify an adapter on a LAN.
Detailed explanation-4: -Switch is a device that takes data sent from one network device and forwards it to the destination node based on MAC address. Switch is a layer 2 device that works using MAC address.
