Computing Dictionary
collision detection definition
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.

This contrasts with
slotted protocols and
token passing.
