Its said that the Turing machine is capable of the most powerful capacity to calculate over any computing mechanism known to man. But I cant figure out how that could be as it appears to me to be the simplest computing machine and nothing more. I has the absolute minimum of all thats required to be a computer:
- A single line (or tape) of one character symbols in its "program code"
- One character capacity of RAM (in the reading head)
-It can only read one symbol or write on symbol at a time
The only thing I can see that makes it complex is the internal instrction set that the reading head uses to react to the symbols it reads. So whats so special about the Turing Machine over any other computing machine?
