| Ethernet, LANs and VLANs Ethernet is used in all parts of the network for point-to-point links between devices, implementing Layers 1 and 2 of the OSI model together. In this module, we’ll review the basic principles of Ethernet and LANs, how it was formalized in the 802 series of standards, the concepts of MAC addresses, MAC frames and broadcast domains. You’ll understand how LAN switches, also called Layer 2 switches, connect devices, and how VLANs separate devices as a basic network security function.
