Fault Tolerance

Definition

Fault tolerance is the ability of a system to continue operating correctly in the presence of faults or failures. This concept is crucial in ensuring reliability and stability, particularly in complex computing systems, where errors can occur due to hardware malfunctions or software bugs. By implementing fault tolerance, systems can automatically detect errors and recover from them, allowing for seamless operation even when components fail.
