Answer / janet

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.

Answer / alex yin

MTBF is applicable for the randam failure caused by
wearout, such as electronics equipment and it is related to
the manufacture. While software wil not wearout and it is
systematic failure one. So, the time domain MTBF is not
applicable to software reliability.

Answer / rahul

Software Reliability is the probability of failure-free software operation for a specified period of time in a specified environment. Software Reliability is also an important factor affecting system reliability.
