‘Codes have traditionally been used to communicate with others in many ways and for a variety of different reasons. A code can be used to communicate a word, sentence or instruction for someone or something else, like a computer, to understand and follow. A code can be communicated across great distances, or without either person having to actually be in the same city, state or country. It can be a secret code, which is unable to be read by anyone who doesn’t have the ‘key’ or understands that specific coding language. One of the most famous historical codes is Morse code.’
