The reliability of the computer system is measured by the average time of no fault (MTTF), that is, the average time the computer system can run normally before a fault occurs. The higher the system reliability, the longer the average fault-free time. Maintainability is measured by the mean service time MTTR), that is, the average time it takes to repair and restore the system to normal after a fault occurs. The better the maintainability of the system, the shorter the average maintenance time.
