The input unit 'digests' the program as it is rece lted and passes it on to the
store in the form of magnetic recording. The store can supply information, or data,
either to the arithmetic unit, the control unit or directly to the output unit, as it is
needed. All the calculations are done in the arithmetic u it. The control unit, which is
the 'nerve center' of the computer, carries out the instruc ions which are received in a
program. The arithmetic unit and the control unit each have small stores of
information called registers. The output unit presents t e results of each computer
operation, usually as a printout.
