System reliability can be measured using various metrics and methods:
1. Mean Time Between Failures (MTBF): This metric measures the average time elapsed between system failures. A higher MTBF indicates better reliability. 2. Mean Time to Repair (MTTR): This metric measures the average time taken to repair a system after a failure. A lower MTTR indicates quicker recovery and higher reliability. 3. Failure Rate: This measures the frequency of system failures over a specified period. A lower failure rate indicates higher reliability. 4. Availability: This metric measures the percentage of time a system is operational and available for use. Higher availability indicates higher reliability.
