IEEE802.3 provides the content of the connection, electrical signals, and media access layer protocols that include the physical layer. Ethernet is currently the most popular LAN technology, it has largely replaced other LAN standards. such as token rings, FDDI and ARCNET. After 100M Ethernet in the end of the century, the rapid development of Gigabit Ethernet and even 10G Ethernet is under the impetus of international organizations and leading enterprises to expand the scope of application.
Common 802.3 applications are:
10M:10base-T (copper UTP Mode)
100M:100base-TX (copper UTP Mode)
100base-FX (fibre optic cable)
1000M:1000base-T (copper UTP Mode)
