What are the three modes of system failure?
A.Your computer can be damaged by power disturbances in three different ways. We call these “the 3 Ds.” They stand for Destruction, Degradation and Disruption. Destruction is the most visible of failure modes because it is usually accompanied by burned or charred components and immediate and catastrophic system failure. Lower magnitude power disturbances do not cause outright failure. Instead they degrade system components–weakening them a little at a time much like rust attacks metal. Usually the damage is not visible until the component fails and then it’s too late. The lowest magnitude of power disturbances are those that interfere with the computer’s ability to make proper logic decisions. These disturbances are associated with normal mode noise and common-mode voltage. These disruptive disturbances are responsible for most of the unexplainable failures that happen from time to time. Disruptive power disturbances are known to cause system lock-ups, lost files, communication errors
