World of Computer Networking Your CCNA start - Types of Media Access Control (MAC) Addresses

The video tutorial explains the three types of MAC addresses used in the data link layer of the TCP/IP model: unicast, multicast, and broadcast. Unicast MAC addresses are unique to each network interface card and are used for direct communication between devices. Multicast MAC addresses allow a group of devices to receive the same data stream, optimizing bandwidth usage. Broadcast MAC addresses are used to send data to all devices in a network. The tutorial also introduces the concept of duplex communication, differentiating between half and full duplex modes.
