IEEE 802.3 standard Part of the institute of Electrical and Electronics Engineers 802 family of LAN standards. The 802.3 standard defines the physical layer (layer 1) and the Medium Access Control (MAC) portion of the data link layer (layer 2). The IEEE 802.3 standard evolved from
Ethernet, but the two networks are not fully compatible with each other.
IEEE 802.5 standard Part of the institute of Electrical and Electronics Engineers 802 family of LAN standards. The 802.5 standard defines the physical layer (layer 1) and the Medium Access Control (MAC) portion of the data link layer (layer 2). Used with Token Ring networks.
IEEE 802.12 standard Part of the institute of Electrical and Electronics Engineers 802 family of LAN standards. The 802.12 standard defines the physical layer (layer 1) and the Medium Access Control (MAC) portion of the data link layer (layer 2).
