Common coding theory

Common coding theory is about finding the most efficient way to store or transmit information. It uses algorithms with instructions for computers to follow when encoding and decoding information so that it gets sent without any errors. Think of it like mail delivery: if you want to send a letter, you put it in an envelope and write the address on the envelope. That's like encoding, which makes sure the letter gets to the right place. Then, when the letter arrives, you take it out of the envelope - this is the decoding - and read it. Common coding theory is how we make sure that our messages get delivered correctly, without any changes or mistakes.
