Software fault tolerance is the ability for software to detect and recover from a fault that is happening or has already happened in either the software or hardware in the system in which the software is running to provide service by the specification. Software fault tolerance is a necessary component to construct the next generation…

Reliability metrics are used to quantitatively expressed the reliability of the software product. The option of which metric is to be used depends upon the type of system to which it applies & the requirements of the application domain. Some reliability metrics which can be used to quantify the reliability of the software product are…

Reliability metrics are used to quantitatively expressed the reliability of the software product. The option of which parameter is to be used depends upon the type of system to which it applies & the requirements of the application domain. Measuring software reliability is a severe problem because we don’t have a good understanding of the nature…

The software failure can be classified as: Transient failure: These failures only occur with specific inputs. Permanent failure: This failure appears on all inputs. Recoverable failure: System can recover without operator help. Unrecoverable failure: System can recover with operator help only. Non-corruption failure: Failure does not corrupt system state or data. Corrupting failure: It damages the system state or data. Software…

Software Reliability means Operational reliability. It is described as the ability of a system or component to perform its required functions under static conditions for a specific period. Software reliability is also defined as the probability that a software system fulfills its assigned task in a given environment for a predefined number of input cases, assuming…
