What does "coding" mean in this context?
- doesnotexist 1y agoCoding being the act of encoding/decoding information from one representation to another. The system itself is called a Code and these are designed to have specific properties like making transmission of information resistant to interference, corruption or interception, etc. "Codes are used for data compression, cryptography, error detection and correction, data transmission and data storage." https://en.wikipedia.org/wiki/Coding_theory https://en.wikipedia.org/wiki/Coding_theory
- iracigt 1y agoThis book in particular is primarily about error correcting codes. Take a message we want to communicate and add some additional data that allows recovering the message even if part of it is corrupted. The hard part is choosing what additional data to include to recover from enough corruption with small overhead and in a reasonable runtime. These are used everywhere from WiFi to hard drives to QR codes to RAM chips -- the ECC in ECC RAM being "error correcting code" and now partially mandatory with DDR5.
