In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver. Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data.

Famous quotes containing the words error and/or correction:
“Still we live meanly, like ants; though the fable tells us that we were long ago changed into men; like pygmies we fight with cranes; it is error upon error, and clout upon clout, and our best virtue has for its occasion a superfluous and evitable wretchedness. Our life is frittered away by detail.”
—Henry David Thoreau (1817–1862)
“Shakespeare, with an improved education and in a more enlightened age, might easily have attained the purity and correction of Racine; but nothing leads one to suppose that Racine in a barbarous age would have attained the grandeur, force and nature of Shakespeare.”
—Horace Walpole (1717–1797)
