How the CPU Works: Fundamentals of Computer Architecture

Ever wondered what actually happens inside a computer when you run a line of code? The Central Processing Unit (CPU) is the brain of the machine, orchestrating every calculation and decision. In this text-based course, you will build a solid mental model of computer architecture, moving from basic logic gates to modern processor designs. What you will learn: - Understand the foundational fetch-decode-execute cycle that drives all computing. - Explore the roles of the Control Unit (CU) and the Arithmetic Logic Unit (ALU). - Learn how registers and memory caches speed up data retrieval. - Compare modern architecture paradigms like RISC and CISC. - Discover how multi-core processing and pipelining allow parallel execution. - Practice tracing instruction execution through written step-by-step exercises. You will begin with foundational terminology and binary logic before exploring internal CPU components and modern performance-boosting techniques. This course is designed for absolute beginners, aspiring software engineers, and hardware enthusiasts with no prior computer engineering background.
