When there are redundancies, an organization tells some of its employees to leave because their jobs are no longer necessary or because the organization can no longer afford to pay them. The ministry has said it hopes to avoid compulsory redundancies
Duplication of system components (e g , hard drives), information (e g , backup tapes, archived files), or personnel intended to increase the reliability of service and/or decrease the risk of information loss
The existence of more than one piece of equipment, any of which could perform a given function These multiple pieces of equipment are used to help improve the reliability and availability of the system Redundancy is generally expressed as the number of pieces of equipment required and the total number available For example, 2 out of 3 means that there are a total of 3 pieces of equipment and 2 pieces are required for proper operation of the system
The existence of more than one means for accomplishing a given function Each means of accomplishing the function need not necessarily be identical The two basic types of redundancy are active and standby Active Redundancy - Redundancy in which all redundant items operate simultaneously Standby Redundancy - Redundancy in which some or all of the redundant items are not operating continuously but are activated only upon failure of the primary item performing the function(s)
Leaving your employment because your employer no longer has work available for you to do Redundancy can be voluntary where employees are offered the choice of leaving, or compulsory, where employees are dismissed
There are no perfect methods of transmitting signals--each one has inherent error rates, and all physical media is subject to damage To safeguard against line and equipment failure during a transmission, a second, redundant line or unit can be active in the background to take over at any time Network administrators always have a redundant (backup) module for multiplexers and other critical equipment
repetition of an act needlessly the attribute of being superfluous and unneeded; "the use of industrial robots created redundancy among workers" (electronics) a system design that duplicates components to provide alternatives in case one component fails repetition of messages to reduce the probability of errors in transmission
- The ability of a system to keep functioning normally in the event of a component failure, by having backup components that perform duplicate functions
A design feature which provides a system with more than one function for accomplishing a given task so that more than one function must fail before the system fails to perform the task Design redundancy requires that a failure in one function does not impair the system's ability to transfer to a second function
(electronics) a system design that duplicates components to provide alternatives in case one component fails repetition of messages to reduce the probability of errors in transmission
Compression is based on the principle that all TV pictures contain redundant information and therefore the quantity of data in a digitised signal can be reduced Redundancy may be: "spatial" - the correlation between adjacent picture elements within the TV frame is used to reduce the data (intraframe compression); "temporal" - only the differences between adjacent frames are processed and encoded (interframe compression); or "statistical" - regularly repeated and therefore predictable information is not transmitted
Portion of the total information contained in a message that can be eliminated without loss of essential information Provision of duplicate, backup equipment or links that immediately take over the function of equipment or transmission lines that fail
Planning in an identical copy of a functional component to serve as backup in case of failure of the primary component relative abundance (of isotopes) - The proportion in a sample of the masses of all naturally occurring isotopes of an element to the mass of the most abundant isotope of that element
The presence of more than one identical item represents redundancy In bioinformatics, the term is used with reference to the sequences in a sequence database If a database is described as being redundant, more than one identical (redundant) sequence may be found If the database is said to be non-redundant (nr), the database managers have attempted to reduce the redundancy The term is ambiguous with reference to genetics, and as such, the degree of non-redundancy varies according to the database manager's interpretation of the term One can argue whether or not two alleles of a locus defines the limit of redundancy, or whether the same locus in different, closely related organisms constitutes redundency Non-redundant databases are, in some ways, superior, but are less complete These factors should be taken into consideration when selecting a database to search
1) The portion of the total information contained in a message that can be eliminated without loss of essential information 2) Providing duplicate devices to immediately take over the function of equipment that fails
The existence of more than one means of accomplishing a given task, where all means must fail before there is an overall failure of the system Parallel redundancy applies to systems in which both means are working at the same time to accomplish the task and either of the systems is capable of handling the job itself in case of failure of the other system Standby redundancy applies to a system in which there is an alternative means of accomplishing the task that is switched in by malfunction-sensing device when the primary system fails
The method of design where a structure is over-designed so that suppport is supplied by more than one method and thus some of the members are 'redundant' (unnecessary)
1) In data transmission, the portion of a message's gross information content that can be eliminated without losing essential information 2) The technique of building in extra identical components, to be used as backups in case the primary components fail
1 In information theory: of a source, the amount by which the logarithm of the number of symbols available at the source exceeds the average information content per symbol of the source
The utilization of modules that are not necessary for normal system operation They are substituted for (or can perform the same function as) another component, allowing the system to remain operational if the component fails
