==Origin==
Latin ''cōdex'' , later spelling of ''caudex'' trunk of a tree, wooden tablet, [[book]], code of [[laws]].
*[http://en.wikipedia.org/wiki/14th_century 14th Century]
==Definitions==
*1: a systematic [[statement]] of a [[body]] of [[law]]; especially : one given statutory [[force]]
*2: a system of [[principles]] or rules <[[moral]] code>
*3a : a system of [[signals]] or [[symbols]] for [[communication]]
:b : a system of [[symbols]] (as [[letters]] or [[numbers]]) used to [[represent]] assigned and often [[secret]] [[meanings]]
*4: [[genetic]] code
*5: a set of instructions for a [[computer]]
==Description==
A '''code''' is a rule for [[converting]] a piece of [[information]] (for example, a [[letter]], [[word]], phrase, or [[gesture]]) into another form or [[representation]] (one sign into another sign), not necessarily of the same type.
In [[communications]] and [[information]] processing, encoding is the [[process]] by which [[information]] from a [[source]] is converted into [[symbols]] to be communicated. Decoding is the reverse process, converting these code symbols back into [[information]] understandable by a receiver.
One reason for coding is to enable [[communication]] in places where ordinary [[spoken]] or [[written]] language is [[difficult]] or impossible. For example, semaphore, where the configuration of flags held signaller or the arms of a [http://en.wikipedia.org/wiki/Semaphore_line semaphore tower] encodes parts of the [[message]], typically individual [[letters]] and [[numbers]]. Another person standing a great distance away can [[interpret]] the flags and reproduce the [[words]] sent.[http://en.wikipedia.org/wiki/Code]
