The Von Neuman architecture is based on the stored-program principle.
This principle describes a computer system with the following components:
1. A processing unit - this contains the arithmetic logic unit and processor registers
2. Control unit - contains the instruction registers and program counters
3. Memory - stores instruction data
4. External mass storage - for external data storage
5. Input and output procedure - for data input and output
