John Von Neumann has never built a computer. Neumann, a Hungarian-american mathematician, has designed a computer from a mathematical point of view. His work led to the design of digital computers from the ’50s.
Today’s computers operate in principle digital computer model envisioned in the ’40s by mathematician John von Neumann. In Neumann’s vision memory was one of the five main parts of a digital computer:
- an input device responsible for entering data into the computer (such as a keyboard)
- a memory for storing data and programs
- arithmetic unit for performing calculations
a control unit which carry out instructions and data transfer between memory and arithmetic unit
- an output device (eg monitor)
