2. Von Neumann Architecture
The von Neumann architecture—also known as the
Von Neumann Model or Princeton Architecture or
Store Memory Architecture. It’s a computer
architecture based on a 1945 description by
Hungarian-American mathematician and physicist
John von Neumann and others in the First Draft of
a Report on the EDVAC.

3. Main Features Of Von Neumann Architecture
 The Von Neumann architecture consists of a single, shared
memory for programs and data.
 A single bus for memory access.
 An arithmetic unit.
 A program control unit.
The Von Neumann processor operates fetching and execution
cycles seriously.

4. Why is Von Neumann architecture used?
Harvard architecture is used primary for small
embedded computers and signal processing .Von
Neumann is better for desktop computers, laptops,
workstations and high performance computers.
Some computers may use advantages from both
architectures.
Typically they use two separated memories.

5. Advantage
 Control Unit retrieves data .
 Instruction in the same manner from one memory.
 Design and development of the Control Unit is simplified,
cheaper and faster.
 Data from input / output devices and from memory are
retrieved in the same manner.
