Answer:
fault tolerance
Step-by-step explanation:
Fault tolerance refers to the property which allows a device to keep working correctly in the case of any of its elements collapsing. When the operation output at all declines, the decline is equal to the extent of the malfunction relative to a foolishly built device in which only a minor malfunction will cause a complete breakdown.
A fault-tolerant architecture allows a process to maintain its planned function, possibly at a decreased pace, instead of crashing entirely when any aspect of the process fails. The concept is more widely used to define information systems configured to keep functioning somewhat fully only, maybe, a decrease in performance or an improvement in reaction time as a result of intermittent malfunction.
