Fast Ethernet
Fast Ethernet is a newer version of Ethernet, supporting data transfer rates of 100 Mbps. Fast
Ethernet is sufficiently similar to Ethernet to support the use of most existing Ethernet
applications and network management tools. The adoption of Fast Ethernet is as 100BASE-T
(over copper) or 100BASE-FX (over fiber).
Fast Ethernet is standardized as IEEE 802.3u.
Gigabit Ethernet
Gigabit Ethernet supports data rates of 1 Gbps. Gigabit Ethernet standards are 1000BASE-T
(over copper) or 1000BASE-ELX, 1000BASE-LX and 1000BASE-SX (over fiber).
Gigabit Ethernet is standardized as IEEE 802.3z.
