This is an introductory course on the architecture of modern computer systems. It introduces the three major components of a computer system, consisting of the processor, memory and input-output control. It describes the main functions of each component and how they interact with each other. It then explores how software interacts with the computer hardware by introducing machine instructions and assembly language programming using a simplified processor.
