block 12 computer architecture

Have you ever wondered what is actually happening inside your computer's processor when you run a program? In this block, you will look deep inside the central processing unit to discover how internal components like the arithmetic logic unit and control unit work together. You will learn the specific roles of dedicated registers, trace the exact steps of the fetch-decode-execute cycle, and explore how buses move data across the system. By writing basic assembly language and comparing different processor architectures, you will see the vital link between high-level software and physical hardware.
