Abstract
This paper will describe the Von Neumann Architecture and explain why it is important. It will describe and explain what a system bus is, and why it is needed in the computer system. A summary of the Boolean operators and the use in computers calculations will be included as well. Finally, a short list of various types of computer storage and memory will be included, and a definition of computer storage.
Keywords: Neumann, Boolean, Memory, Storage, System, Bus

John Von Neumann was born in 1903 in Budapest. He studied mathematics and graduated from the Pázmány Péter University in Budapest with a Ph.D. In 1930 he was invited to the University of Princeton to teach mathematics in the Institute for Advance Study of Princeton. Von Neumann possessed an extraordinary memory, he was a gifted man that made multiple contributions to the math world, and the computer world, but perhaps his biggest contribution is the creation of the Von Neumann Architecture. The Von Neumann architecture stated that a computer was able to have an uncomplicated, established structure, able to execute any calculation when given the proper command. The Model of this architecture is comprised of the following components, the memory, the control unit, the arithmetic logic unit (ALU).
The memory was used to store the information from the ALU or processing unit. This communication was done by two registers, the memory address register (MAR), and the memory data register (MDR). These registers performed all the reads and writes executed by the computer. There are two key operations on memory, one is the fetch that puts and address into the MAR, then tells the memory to load, and finally copies the data into the MDR. The second one is store, first the
