Hardware Failures<br />
The system is said to have a failure when its actual behaviour<br />
deviates from the intended one specified in design documents<br />
Underlying faults: the largest part of hardware failures caused by<br />
physical wear-out or physical defect of a component<br />
• transient faults: the faults that may occur and then disappear after<br />
some period of time<br />
• permanent faults: the faults that remain in the system until they<br />
are repaired<br />
• intermittent faults: the reoccurring transient faults
