Explanation:
Detailed explanation-1: -Software reliability, like hardware reliability, is defined as the probability that the software system will work without failure under specified conditions and for a specified period of time.
Detailed explanation-2: -Software availability is measured in terms of mean time between failures (MTBF). MTBF consists of mean time to failure (MTTF) and mean time to repair (MTTR). MTTF is the difference of time between two consecutive failures and MTTR is the time required to fix the failure.
Detailed explanation-3: -Software reliability was defined in two ways. The probability of failure-free operation of a system for a specified time in a given environment. Failure intensity is a measure of reliability.
