Detailed explanation-1: -Reliability is defined as the probability that a product, system, or service will perform its intended function adequately for a specified period of time, or will operate in a defined environment without failure.
Detailed explanation-2: -Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).
Detailed explanation-3: -Reliability is maintaining the level of quality over time. Consistency is making sure every system is as consistent as possible. Accuracy allows the system to do what it’s supposed to do within a very tight bandwidth of performance characteristics.
Detailed explanation-4: -Reliability refers to how consistently a method measures something. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable.
