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.
