About Ethernet

Ethernet is a Local Area Network (LAN)-based network communication technology. Ethernet follows the IEEE802.3 protocol standards, and includes the Ethernet speed ranges of 10 M, 100 M and 1,000 M. In the TCP/IP protocols, Ethernet is located in the following layers.

Ethernet is relevant to the physical layer (L1) and the data link layer (L2) in the TCP/IP layers. The data link layer contains the Logic Link Control (LLC) sub-layer and the Multimedia Access Control (MAC) sub-layer.
