What is Software reliability?

It is the probability that software will work without failure for a specified period of time in a specified environment.Reliability of software is measured in terms of Mean Time Between Failure (MTBF). For eg if MTBF = 10000 hours for an average software, then it should not fail for 10000 hours of continous operation.
