Architecture - Von Neumann
About
The Von Neumann organization is the most and well known organization (a sort of reference).
It implements a instruction cycle (fetch, decode, execute, store) with the following components:
- the CPU to fetch instructions from main memory and execute
- the memory to store program code and data
- One or more bus. Today, a computer has several buses, each specialized in a type of traffic:
- the data bus to transfer data,
- the address bus to transmit the location information,
- the control bus to provide information as to how data is being sent
- I/O Devices:
- input device to give input to the computer: keyboard, mouse, sensor, etc
- output device to take information from the CPU: monitor, LED , …
The data does not move. Only the instruction pointers
