Redundancy
« on: April 21, 2015, 05:11:54 AM »
In information technology, the term redundant has several usages:

1) Redundant describes computer or network system components, such as fans, hard disk drives, servers, operating systems, switches, and telecommunication links that are installed to back up primary resources in case they fail.
 A well-known example of a redundant system is the redundant array of independent disks (redundant array of independent disks).

2) Redundant information is unneeded or duplicated information.

3) Redundant bits are extra binary digits that are generated and transferred along with a data transfer to ensure that no bits were lost during the data transfer.

Redundancy is the quality of a system, an item of information, or a bit that is redundant.

In computer main memory, auxiliary storage and computer buses, data redundancy is the existence of data that is additional to the actual data and permits correction of errors in stored or transmitted data. The additional data can be simply a complete copy of the actual data, or only select pieces of data that allow detection of errors and reconstruction of lost or damaged data up to a certain level.

Definition - What does Network Redundancy mean?

Network redundancy is a process through which additional or alternate instances of network devices, equipment and communication mediums are installed within network infrastructure. It is a method for ensuring network availability in case of a network device or path failure and unavailability. As such, it provides a means of network failover

redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe.

Redundancy is a system design in which a component is duplicated so if it fails there will be a backup. Redundancy has a negative connotation when the duplication is unnecessary or is simply the result of poor planning.
