# Communication

> *In communications and information processing, code is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form or representation, sometimes shortened or secret, for communication through a communication channel or storage in a storage medium.* [Wikipedia](https://en.wikipedia.org/wiki/Code)
