Differentiate between Ethernet, Fast Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet? Fast Ethernet is a local area network transmission standard that provides a data rate of 100 megabits per second and it can negotiate speed (10 or 100) and duplex (half or full) with the other side of the link,moreover Fast Ethernet provides faster throughput for video, multimedia, graphics, Internet surfing and stronger error detection and correction.whereas Ethernet is the most widely-installed local area network technology.,which can provide data transfer rate of 3 ~10 Mbps and usually doesn't provide auto-negotiation. In Gigabit" Ethernet, data transfer rates peak at 1000 mbps and with10 Gigabit Ethernet standard,which was published in 2002 as IEEE Std 802.3,It defines a version of Ethernet with a nominal data rate of 10 Gbit/s, ten times as fast as Gigabit Ethernet.many attributes of 1000 mbps Ethernet are retained in the 1000BASE-T standards.
