<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Redundancy&#039;&#039;&#039; is a concept that refers to the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe.<br /> <br /> == Overview ==<br /> In [[engineering]], redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the case of a backup or fail-safe. In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated, which is formally termed triple modular redundancy (TMR).<br /> <br /> == Types of Redundancy ==<br /> There are several types of redundancy, including hardware, information, time and software redundancy.<br /> <br /> === Hardware Redundancy ===<br /> [[Hardware redundancy]] is the duplication of physical components. In computer systems, this can be as simple as adding an extra hard drive, or as complex as designing a fault-tolerant system that can continue operation even when a major component or system fails.<br /> <br /> === Information Redundancy ===<br /> [[Information redundancy]] is the repetition of data in a database or other storage system. This can be used to protect against data loss, as well as to improve the performance of certain operations.<br /> <br /> === Time Redundancy ===<br /> [[Time redundancy]] involves performing the same operation multiple times. This can be used to check for errors and ensure that the correct result is obtained.<br /> <br /> === Software Redundancy ===<br /> [[Software redundancy]] is the use of multiple versions of the same software, running on different systems or in different locations. This can be used to protect against software bugs or failures.<br /> <br /> == See Also ==<br /> * [[Fault tolerance]]<br /> * [[High availability]]<br /> * [[Reliability engineering]]<br /> * [[Safety engineering]]<br /> <br /> [[Category:Engineering concepts]]<br /> [[Category:Reliability engineering]]<br /> [[Category:Safety engineering]]<br /> {{stub}}</div>
