5 Questions
Explain the difference between faults, errors, and failures in the context of reliability engineering.
Faults are characteristics of a system that can lead to errors. Errors are erroneous system states that can lead to unexpected behavior. Failures are the observable incorrect system behavior as a result of errors.
What are some examples of critical systems with high reliability requirements?
Medical systems, telecommunications and power systems, aerospace systems
How do software customers' expectations vary for non-critical applications versus critical applications?
For non-critical applications, customers may be willing to accept some system failures, while for critical applications, they expect very high reliability.
What is a system fault in the context of reliability engineering?
A system fault is a characteristic of a software system that can lead to a system error.
Provide an example of human error or mistake that can introduce faults into a system.
In a wilderness weather system, a programmer might decide to compute the time for the next transmission by simply adding 1 hour to the current time, which can lead to issues when the transmission time is between 23.00 and midnight.
