REDUNDANCY CHECK Meaning and
Definition
-
A redundancy check refers to a computational method or technique used to ensure the accuracy and integrity of data during its transmission or storage. It is a form of error control, where a specific algorithm or mathematical formula is applied to verify the correctness of data by comparing it to a known or expected value.
The redundancy check works by calculating a specific value, often referred to as a checksum or hash, from the data being transmitted or stored. This value is then appended to the original data, forming a composite string. The receiving or retrieving end can perform the same calculation on the received data and compare the calculated value with the appended one. If they match, it indicates that the data has been transmitted or stored correctly.
One common example of a redundancy check is the parity check, which involves adding an additional bit, known as a parity bit, to a group of bits. The parity bit is set in such a way that the total number of bits becomes either an even or odd number, depending on a predefined rule. By checking the parity bit at the receiving end, errors in the data can be detected.
Redundancy checks have wide applications in various fields, including computer networks, data storage systems, telecommunications, and digital communication protocols. They play a crucial role in ensuring the reliable transmission and storage of data, minimizing the chances of errors and ensuring data integrity.

Etymology of REDUNDANCY CHECK
The term "redundancy check" is derived from the combination of two main words: "redundancy" and "check".
1. Redundancy: The word "redundancy" originated from the Latin word "redundantia", which means "overflowing" or "excess". In English, redundancy refers to the inclusion of extra or unnecessary elements that may be superfluous but are added as a precautionary measure for reliability purposes.
2. Check: The word "check" has multiple etymological roots, but in the context of "redundancy check", it refers to the act of verification or evaluation. This usage of "check" is derived from the Old French word "eschec" or "echequier", meaning "to checkmate" or "to examine".
