The architecture of the "Mailüfterl" was based on a John
Neumann machine. John von Neumann had thought about what the ideal
computing machine should look like.
In his opinion it should consist of the following units:
arithmetic unit (carries out calculation processes)
control unit (manages/controls everything; knows how to carry out orders)
memory ( stores intermediate date)
input and output devices (input by means of a rotary switch)
