What is code ?

For the purposes of communication and information processing, a code is a set of principles that technology is getting as a letter, word, sound, picture, or gesture—into another form, often shorter or secret, for storage on a storage device or for transmission over a channel of communication. An early example is the development of language, which allowed people to express verbally what they were thinking, seeing, hearing, or feeling to others. However, speaking restricts the audience to those present at the time the speech is delivered and limits that range of communication towards the distance a voice may travel. The ability to communicate across space and time was greatly expanded by the discovery of printing, which converted spoken language into pictorial symbols.
