| carrier sense multiple access
collision detect
Media-access mechanism wherein devices ready to transmit
data first check the channel for a carrier. If no carrier is sensed for a
specific period of time, a device can transmit. If two devices transmit at
once, a collision occurs and is detected by all colliding devices. This
collision subsequently delays retransmissions from those devices for some
random length of time. CSMA/CD access is used by Ethernet and IEEE 802.3.
