CSMA/CD bliver det kun brugt i Ethernet???

Nu har jeg fundet et svar, det er et citat fra cisco:

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.
