Quizplus · Accepted Answer

Redundancy refers to the presence of backup or duplicate components within a system, which improves its reliability and fault tolerance. It provides surplus capacity that can kick in when the primary component fails or experiences problems. Redundancy is often used in critical systems that need to operate continuously, such as power grids, air traffic control systems, or data centers. Redundancy is not related to providing choices, software versions, or managing users in a domain.
