Reliability is the measure of how long a resource performs its intended function and is measured in percentage of up-time.
True
False

A

False
The correct answer is false. Reliability is the measure of how long a resource performs its intended function. It is normally measured in a unit of time (hours/days/weeks) since the last failure (MTBF, or Mean Time Between Failures). Availability is measured in terms of up-time. These two terms are very related but both need to be taken into account. For example, if a system goes off-line for 1 minute every day it may have relatively high availability (99.93%) but very low reliability.
