A picture showing scratches on the readable surface of a CD-R. Music and data CDs are coded using error correcting codes and thus can still be read even if they have minor scratches using error detection and correction.
Charles Babbage, sometimes referred to as the "father of computing".
To clean up transmission errors introduced by Earth's atmosphere (left), Goddard scientists applied Reed–Solomon error correction (right), which is commonly used in CDs and DVDs. Typical errors include missing pixels (white) and false signals (black). The white stripe indicates a brief period when transmission was interrupted.
Ada Lovelace published the first algorithm intended for processing on a computer.

In information theory and coding theory with applications in computer science and telecommunication, error detection and correction (EDAC) or error control are techniques that enable reliable delivery of digital data over unreliable communication channels.

- Error detection and correction

Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory and automation) to practical disciplines (including the design and implementation of hardware and software).

- Computer science

The field is at the intersection of probability theory, statistics, computer science, statistical mechanics, information engineering, and electrical engineering.

- Information theory

Applications of fundamental topics of information theory include source coding/data compression (e.g. for ZIP files), and channel coding/error detection and correction (e.g. for DSL).

- Information theory

Codes are used for data compression, cryptography, error detection and correction, and more recently also for network coding.
