How digital information survives the constant threat of corruption
In short: We rarely notice computer glitches, yet hardware is constantly failing. This lecture explores the mathematical secrets behind Error Control Coding, the technology that allows data to detect and fix its own errors.
Richard Harvey explains the mechanisms that ensure the integrity of our digital lives. Despite the appearance of seamlessness, disks, Wi-Fi signals, and internet packets are all subject to continual corruption. Error Control Coding provides a way to store or transmit information so that it can identify when it has been compromised and subsequently correct itself.
