Fault tolerance is that the property that allows a system to continue operating properly within the event of the failure of (or one or more faults within) variety of its components. If it’s operating quality decreases within the least, the decrease is proportional to the severity of the failure, as compared to a naively designed system, during which even a little failure can cause total breakdown. Fault tolerance is especially wanted in high-availability or life-critical systems. The ability of maintaining functionality when portions of a system break down is mentioned as graceful degradation.
