collision detection
<networking> A class of methods for sharing a data transmission medium in
which hosts transmit as soon as they have data to send and then check to see
whether their transmission has suffered a collision with another host's.
If a collision is detected then the data must be resent. The resending algorithm
should try to minimise the chance that two hosts's data will repeatedly collide.
For example, the CSMA/CD protocol used on Ethernet specifies that they should
then wait for a random time before re-transmitting.
See also backoff.
This contrasts with slotted protocols and token passing.
