Reliability means that
data are reasonably complete and accurate, meet your intended purposes, and are not subject to inappropriate alteration.
Reliability is "the property of leading to consistent intended behaviour and results."
the probability that a service will perform its required function for a specified period of time under stated conditions.
the likelihood that a
system will perform its intended function within the context it was designed to operate within.
the ability of a
system to perform and maintain its functions in routine circumstances as well as hostile or unexpected circumstances.
A decision that
computer-processed data are reliable does not necessarily mean that the data are error-free. Errors are considered acceptable in this circumstance: You have assessed the associated risk and conclude that the errors are not substantial enough to cause a reasonable person, aware of the errors, to doubt a finding, conclusion, or recommendation based on the data.
Reliability focuses on a
system's ability to perform as intended, despite apparently random hardware and software failures.
