6 HARDWARE PREAMBLE: What Kind of Machine Do We Want? It will take input and produce a desired output (I/O) Put another way, it will execute algorithms. That is, it will store programs and data, execute the steps sequentially, and produce an output for an associated input. That means, it will require memory, a “processor,” the ability to perform basic functions (like arithmetic/logic), etc.
7 DEFINITION: Von Neumann Architecture The Von Neumann architecture is a model for designing and building computers that is based on the following THREE CHARACTERISTICS: 1. Four major subsystems called MEMORY , Input/Output (I/O), Arithmetic/Logic Unit (ALU), and the Control Unit (CU).
