Gigabit Ethernet(GE)

Gigabit Ethernet is the IEEE 802.3 Ethernet standard extension, the transmission speed of 1000 megabits per second (ie 1Gbps). Initially used in large campus network, can make existing 10Mbps Ethernet and 100Mbps Fast Ethernet link. It can replace the 100Mbps FDDI network, ATM technology is a strong opponent.
 Between switches support Gigabit Ethernet, full duplex switch with terminal connection between the support half-duplex shared network connection, using repeaters and CSMA / CD collision detection mechanism.
