- Reliability
-
An abstract term defined as the probability that a product or system performs its intended function for a specified time period when operating under normal environmental conditions. Reliability differs from availability in that reliability involves only one event, failure, whereas availability takes into account two events: failure and recovery. A system can be highly available yet experience frequent periods of inoperability as long as the length of each period is short.
