IEEE 802.3 | IEEE Ethernet Standards 802.3 family
This page describes IEEE 802.3 family of ethernet standards.It covers all the versions of IEEE 802.3 standards.
As we know ethernet physical layer is used in local area networks for communication between the nodes. IEEE 802.3 standard family defined various ethernet physical layers used for data communication. The table below mentions basic descriptions of each of these IEEE 802.3 standards.
Physical layer sits at layer-1 of the OSI stack. Refer OSI vs TCPIP layers for functions of each of the OSI layers. MAC resides on layer-2 of the OSI stack.
IEEE 802.3 specifications are produced by the working group and IEEE community. It defines PHY and MAC layers. In the LAN, physical connections between various nodes and other networking devices such as router, switches and Hubs are made using either copper cable or fiber optic cable.

As mentioned each of the IEEE 802.3 sub-standard has speed and medium type associated with them. Refer Ethernet tutorial which describes ethernet frame types (DIX,802.3), CSMA/CD protocol, topologies, Ethernet testing and more.
