Fault Tolerance

Fault Tolerance is a system design principle that enables a system to continue operating properly in the event of a component failure. It is a measure of the system's ability to withstand unexpected errors or faults without causing a system crash or data loss. Fault tolerance is achieved by using redundant components, such as multiple power supplies, multiple processors, or multiple storage devices, to ensure that the system can continue to operate even if one component fails. Fault tolerance is an important consideration in the design of mission-critical systems, such as those used in aerospace, medical, and military applications.
