MTBF stands for Mean Time Between Failures, and is a measure of the reliability of a system or component. It is the average time that a system or component can be expected to operate without failure. MTBF is typically expressed in hours, but can also be expressed in other units such as miles or cycles. The higher the MTBF, the more reliable the system or component is. MTBF is an important metric for businesses, as it can help them determine the expected life of a system or component, and can be used to inform decisions on when to replace or upgrade components. MTBF can also be used to compare the reliability of different systems or components, and can be used to inform purchasing decisions.
