the calculation is repeated and, in the event the check values do not match, corrective action can be taken against data corruption. CRCs are so called because the check https://www.researchgate.net/publication/224095710_Double_Bits_Error_Correction_Using_CRC_Method (data verification) value is a redundancy (it expands the message without adding information) and the algorithm is based on cyclic codes. CRCs are popular because they are simple to implement in binary hardware, easy to analyze mathematically, and particularly good at detecting common errors caused by noise in transmission channels. Because the check value has a fixed length, https://en.wikipedia.org/wiki/Cyclic_redundancy_check the function that generates it is occasionally used as a hash function. The CRC was invented by W. Wesley Peterson in 1961; the 32-bit CRC function of Ethernet and many other standards is the work of several researchers and was published in 1975.

The use of systematic cyclic codes, which encode messages by adding a fixed-length check value, for the purpose of error detection in communication networks, was first proposed by W. Wesley Peterson in 1961.[1] Cyclic codes are not only simple to implement but have the benefit of being particularly well suited for the detection of burst errors, contiguous sequences of erroneous data symbols in messages. This is important because burst errors are common transmission errors in many communication channels, including magnetic and optical storage devices. Typic

An Algorithm for Error Correcting Cyclic Redundance Checks Programmers have used the Cyclic Redundance Check (CRC) algorithm for years to uncover errors in a data transmission. It turns out that you can also use CRCs to correct a single-bit error in any transmission. I first heard about error correcting CRCs in a conversation I cyclic redundancy had several years ago [1]. At the time, I thought this feature of CRCs was general knowledge, but as I did more research, I saw no mention of CRC error correction in the popular literature. The traditional response to a CRC error is re-transmission. However, the advance of computer technology has led to some situations where cyclic redundancy check it is actually preferable to correct single-bit errors rather than to resend. Some examples include: Satellite transmission -- If a host is sending data via a satellite, the cost of sending a regular packet is high, so the cost of a resend just doubles the price for the packet. High-speed transmission -- In the future, there may be a tendency to push the technology. (Let's crank this baby up and see what it will do.)The faster bits move through a medium, the higher the probability of error. PowerLine Carriers -- Metricom Corporation, a supplier of integrated circuits for computer applications states, "There is a growing interest in the use of PowerLine Carrier (PLC) for data communication using the intrabuilding electric power distribution circuits. Power lines were not designed for data communications and exhibit highly variable levels of impedance, signal attenuation and noise... Harmful effects of impulse noise on data communications systems can be expected." [2]. You could also use CRC error correction for stora
