Software Reliability Models

The reliability is one very important parameter of electronic devices, hardware, and applications software. We review in this paper basic reliability terms, software reliability models -predictive models, assessment models. We try to explain basic principles of software reliability models, their practical using in technical activities. We show also key assumptions on which software reliability models are based, specific assumptions related to each specific software reliability model and some examples of concrete software reliability models. In conclusions there are summary of knowledge about software reliability models.
