Reliability
For computer systems reliability is how well it does what is expected of the system before failing
- The reliability of a computer system can be measured with AVAIL and MTTF
- AVAIL is the percentage of time the system is available to the user taking away the percentage of time need for maintenance. e.g after 100 hours, the computer was available for 95 hours out of 100 then the AVAIL figure would be 95%
- MTTF stands for Mean Time To Fail. MTTF is the average amount hours the system runs before it breaks.
- The reliability of a computer system can be measured with AVAIL and MTTF
Consequences of unreliable systems
- People using unreliable systems may lose all of their data, for example family photos.
