error-correcting code

Webster's Dictionary (1913)

Computers A set of symbols used to represent blocks of binary data, in which the original block of data is represented by a larger block of data which includes additional bits arranged in such a way that the original data may be read even if one or more of the bits of the encoded data is changed, as in a noisy communicaiton channel. Various codes are available which can correct different numbers or patterns of errors in the transmitted data. Such codes are used to achieve higher accuracy in data transmission, and in data storage devices such as disk drives and tape drives.
