61Data corruption — Photo data corruption; in this case, a result of a failed data recovery from a hard disk drive Data corruption refers to errors in computer data that occur during writing, reading, storage, transmission, or processing, which introduce unintended… …
62Linear code — In mathematics and information theory, a linear code is an important type of block code used in error correction and detection schemes. Linear codes allow for more efficient encoding and decoding algorithms than other codes (cf. syndrome… …

65Hamming bound — In mathematics and computer science, in the field of coding theory, the Hamming bound is a limit on the parameters of an arbitrary block code: it is also known as the sphere packing bound or the volume bound from an interpretation in terms of… …
66Mathematics of CRC — Cyclic Redundancy Check (CRC) is based on division in the ring of polynomials over the finite field GF(2) (the integers modulo 2), that is, the set of polynomials where each coefficient is either zero or one, and arithmetic operations wrap around …
