The two most prominent LAN technologies in use today are Ethernet (supports bandwidths of up to 100 Gbps equivalent to 100,000 Mbps) and WLAN.
Ethernet operates in the data link layer and the physical layer. Ethernet sublayers are related to the frame fields. The Ethernet MAC address is used and a MAC address table is built up in a switch. On the switch ports there is forwarding methods and port settings available on Layer 2. Also switch speeds come into the methods.
