|2.94&nbsp;[[Mbit/s]] (367&nbsp;[[kilobyte|kB]]/s) over a [[coaxial cable]] (coax) [[bus network|bus]]. A single-octet node address is unique only to an individual network.

| rowspan="2" |10&nbsp;Mbit/s (1.25&nbsp;[[megabyte|MB]]/s) over thick coax. Frames have a Type field. This frame format is used on all forms of Ethernet by protocols in the [[Internet protocol suite]]. Six-octet [[MAC address]].

Same as Ethernet&nbsp;II (above) except Type field is replaced by Length, and an [[IEEE 802.2|802.2]] LLC header follows the 802.3 header. Based on the [[CSMA/CD]] media access method.
