When was the last time you opened a file and noticed a computer glitch? “Never” is the usual answer. Yet the underlying hardware makes continual errors: disks make errors, the internet loses packets of data, wifi signals get corrupted and so on.

This lecture is about the secrets of the mysterious invulnerability that is Error Control Coding: a way of storing or transmitting information such that it knows it has been corrupted and can correct itself.

A lecture by Richard Harvey
