Turing machines can model all the computations that can be performed on a computing machine.
His [John von Neumann] basic design, now known as a von Neumann machine, was used in the EDSAC, the first stored program computer, and is still the basis for nearly all digital computers, even now, almost half a century later. ... Each word held either two 20-bit instructions [a stored program] or a 39-bit signed integer.
Most people can remember that the abbreviations for add, subtract, multiply, and divide are ADD, SUB, MUL, and DIV, but few can remember that the machine instructions (for the PDP-11) are 24576, 57344, 28672, and 29184.
