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.
