|(networking)||collision detection - 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.

This contrasts with slotted protocols and token passing.
