Software Reliability
Software reliability is the probability that the software will operate failure-free for a specific period of time in a specific environment. It is measured per some unit of time.
- Software Reliability starts with many faults in the system when first created.
- After testing and debugging enter a useful life cycle.
- Useful life includes upgrades made to the system which bring about new faults.
- The system needs to then be tested to reduce faults.
- Software reliability cannot be predicted from any physical basis, since it depends completely on the human factors in design.
Software Engineering – Hardware Reliability vs Software Reliability
Reliability in software is software that has no failure and works in a special time period with a special environment. Hardware reliability is the probability of the absence of any hardware-related system malfunction for a given mission on the other hand software reliability is the probability that the software will provide a failure-free operation in a fixed environment for a fixed interval of time. The article focuses on discussing the difference between Hardware Reliability and Software Reliability.
