Code, of course, is a word with a long history, and it pops up again during the history of the telegraph, because if Samuel Morse contributed one real invention, it wasn't the electrical telegraph, it was the Morse code. It was a solution to the problem of converting information from one form to another - in his case, from the form of a written alphabet into another form that was suitable for sending across electrical wires as pulses. That was a tricky problem and it’s a problem that was solved in a different way through a process of social evolution by drummers in Africa. And yet, it is the same problem that, when solved, leads to the creation of information theory, the understanding that information exists on different levels, in different forms and needs to be converted from one to another. That is an understanding that really is summed up in a single word, and the word is code.
