[10] On modern personal computers, users often want to run several applications at once.
For example, electricity that is delivered without interruptions (blackouts, brownouts or surges) 99.999% of the time would have 5 nines reliability, or class five. [10] In particular, the term is used in connection with mainframes [ 11 ] [ 12 ] or enterprise computing, often as part of a service-level agreement .
