graceful degradation

   Also found in: Wikipedia 0.02 sec.

graceful degradation

A system that continues to run at some reduced level of performance after one of its components fails. It is a level below fault-tolerant systems, which continue running at the same rate of speed. For example, a two-computer complex employing graceful degradation would be reduced to using one system if the other fails. With fault tolerance, a third computer would be standing by to take over in the event of failure. See fault tolerant.


graceful degradation [′grās·fu̇l ‚deg·rə′dā·shən]
(computer science)
A programming technique to prevent catastrophic system failure by allowing the machine to operate, though in a degraded mode, despite failure or malfunction of several integral units or subsystems.
