This is the IEEE 802.3
networking standard that uses carrier sense multiple access with collision detection
(CSMA/CD). An Ethernet device that wants to transmit first checks the channel for a carrier,
and if no carrier is sensed within a period of time, the device transmits. If two devices
transmit simultaneously, a collision occurs. This collision is detected by all transmitting
devices, which subsequently delay their retransmissions for a random period. Ethernet runs
at speeds from 10 Mbps to 10 Gbps on full duplex.
