Geographic redundancy corrects the vulnerabilities of redundant devices deployed by geographically separating backup devices. Geographic redundancy reduces the likelihood of events such as power outages, floods, HVAC failures, lightning strikes, tornadoes, building fires, wildfires, and mass shootings disabling most of the system if not the entirety of it.
While different in nature, data redundancy also occurs in database systems that have values repeated unnecessarily in one or more records or fields, ...
Redundancy (information theory), the number of bits used to transmit a message minus the number of bits of actual information in the message; Redundancy in total quality management, quality which exceeds the required quality level, creating unnecessarily high costs; The same task executed by several different methods in a user interface
Gene redundancy is the existence of multiple genes in the genome of an organism that perform the same function. Gene redundancy can result from gene duplication . [ 1 ] Such duplication events are responsible for many sets of paralogous genes. [ 1 ]
Redundancy of compressed data refers to the difference between the expected compressed data length of messages () (or expected data rate () /) and the entropy (or entropy rate ). (Here we assume the data is ergodic and stationary , e.g., a memoryless source.)
Voluntary redundancy is when an employer asks an employee to agree to terminate their contract, in return for a financial incentive.
Genetic redundancy is a term typically used to describe situations where a given biochemical function is redundantly encoded by two or more genes. In these cases, mutations (or defects) in one of these genes will have a smaller effect on the fitness of the organism than expected from the genes’ function.
Two kinds of redundancy are passive redundancy and active redundancy. Passive redundancy is used to achieve high availability by including enough excess capacity in the design to accommodate a performance decline. The simplest example is a boat with two separate engines driving two separate propellers.
