Turing machines in a V neumann architecture

Hi, last time in my informatic class we were talking about, how does a computer machine works, so here I explain it very completly and easy: A turing machine is simply a "little box" that is over a tape which is divided into ones and zeros in an irregular order looking at one square at the time. Receives an instruction or an information from the user. This box has a little programm book that has the information, and tells him what to do. Like on the tape it has to change the number which is looking at the moment or just leave it and move to another square on the tape. And that´s how the machine does for answer the question that we did.

This is the theory made by Allan Turing in 1936.
