Editing Channel Coding (section)

* '''Channel Coding''' — The process of adding redundancy to a message so that errors caused by the channel can be detected and corrected.
* '''Noise''' — Random interference in a communication channel (static, heat, radio interference).
* '''Error Correction Code (ECC)''' — A mathematical code that allows a receiver to "Repair" a broken bit.
* '''Check-sum''' — A simple number added to the end of a message to detect if any bits changed (but not necessarily fix them).
* '''Parity Bit''' — A single bit added to a string to ensure the total number of "1s" is even or odd.
* '''Hamming Distance''' — The number of bits that are different between two messages (the "Gap" between codes).
* '''Block Code''' — A code that breaks a message into fixed-size "Chunks" and adds extra bits to each chunk.
* '''Convolutional Code''' — A code that processes a continuous stream of bits and uses the "Memory" of previous bits to protect current ones.
* '''Reed-Solomon Code''' — A powerful code used in CDs, DVDs, and QR codes that can fix "Bursts" of many errors in a row.
* '''Shannon's Channel Capacity''' — The maximum rate at which information can be sent over a channel with zero errors.
