10 Facts About Error correction

Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data in many cases.

Error correction detection is the detection of errors caused by noise or other impairments during transmission from the transmitter to the receiver.

Error correction is the detection of errors and reconstruction of the original, error-free data.

Forward error correction is a process of adding redundant data such as an error-correcting code to a message so that it can be recovered by a receiver even when a number of errors are introduced, either during the process of transmission or on storage.

Error correction-correcting codes are used in lower-layer communication such as cellular network, high-speed fiber-optic communication and Wi-Fi, as well as for reliable storage in media such as flash memory, hard disk and RAM.

Whereas early missions sent their data uncoded, starting in 1968, digital error correction was implemented in the form of convolutional codes and Reed–Muller codes.

Error detection and correction codes are often used to improve the reliability of data storage media.

Error correction-correcting memory controllers traditionally use Hamming codes, although some use triple modular redundancy.
