Von Neumann Paper

John von Neumann was a Hungarian-American pure and applied mathematician, physicist, and polymath. He made major contributions to a number of fields, including mathematics, physics, economics, computing and statistics. The basic concept behind the von Neumann architecture is the ability to store program instructions in memory along with the data on which those instructions operate. The von Neumann machine was developed by John Von Neumann and others in the 1940s that allow for input, output, processing and memory. Until von Neumann proposed this possibility, each computing machine was designed and built for a single predetermined purpose. All programming of the machine required the manual rewiring of circuits, a tedious and error-prone process. If mistakes were made, they were too difficult to detect and hard to correct.
The von Neumann architecture is comprised of three sub-systems or distinct components which are the central processing unit aka the CPU, memory and input/output interfaces. Here’s a breakdown of each component and how it coincides with the von Neumann architecture.
The CPU, which is considered the heart of the computer, includes three main components of itself: the control unit, one or more arithmetic logic units and various registers. The control unit will manage the process of moving data and program into and out of memory and also deal with carrying out program instructions one at a time. It works in sequential order which means the first one that was input will be the first one processed. The second component that I will be discussing will be the memory. The computer’s memory is used to store program instructions and data. In more modern computers, this is referred to as RAM (random access memory). RAM is temporary and its contents can be changed at anytime and is erased when the computer is turned off. ROM (read only memory) is another type of memory that is permanent and is used to store the initial boot up instructions of
