Software reliability can provide the assurance for the better software processes, which are performing the task in particular situations within a time frame. This feature ensures the user the software performance. It also affects the reliability of the system. Users can scale the software quality according to this feature. The system consists of software and hardware and reliability of both having the difference. Various programming concepts and languages are in the market, which decide the reliability of software at major content. This chapter provides a detailed study of different types of reliability and its models, which are responsible for software reliability measurements. As every model has different criteria, so no single model is perfect. It also provides the information about software quality improvement.
