In general, reliability (systemic def.) is the ability of a person or system to perform and maintain its functions in routine circumstances, as well as hostile or unexpected circumstances.
The IEEE defines it as ". . . the ability of a system or component to perform its required functions under stated conditions for a specified period of time."
Reliability may refer to:
- Reliability (statistics), of a set of data and experiments
- High reliability is informally reported in "nines"
- Reliabilism in philosophy and epistemology
- Data reliability, a property of some disk arrays in computer storage
- Reliability engineering ensures a system will be reliable when operated in a specified manner
- Reliability theory, as a theoretical concept, to explain biological aging and species longevity
- Reliability (computer networking), a category used to describe protocols
