Ethernet A local-area network (LAN) architecture using a
bus or star topology and supporting data transfer rates of
10 Mbps. It is one of the most widely implemented LAN
standards. A newer version of Ethernet, called 100Base-T
(or fast Ethernet), supports data transfer rates of 100 Mbps.
The 802.11a and 802.11b protocols are often referred to as
“wireless Ethernet.”
