Computer Architecture and Organization: Core Principles and Exam Prep

Understanding how hardware executes software is the key to writing efficient code and passing rigorous computer science examinations. This text-based course guides you through the inner workings of modern computer systems from the ground up. You will transition from writing code to understanding exactly how instructions are fetched, decoded, and executed by the CPU. By mastering these core hardware principles, you will gain the analytical skills required for academic tests, technical interviews, and systems-level engineering. What you'll learn: - Learn the fundamental structure of computer systems, including the von Neumann architecture and system buses. - Master binary arithmetic, data representation, and how digital logic gates build complex arithmetic logic units. - Understand instruction set architectures, addressing modes, and the differences between CISC and RISC paradigms, including modern RISC-V concepts. - Analyze memory hierarchies, cache mapping techniques, virtual memory, and modern cache coherency protocols. - Explore CPU design, pipelining, hazards, and how modern processors achieve instruction-level parallelism. - Practice solving typical exam-style problems on memory addressing, performance metrics, and pipeline execution. The course starts with essential terminology and basic digital logic before moving systematically through CPU design, instruction sets, and memory management. You will read clear explanations, study detailed text schematics, and work through step-by-step written exercises designed to reinforce key concepts. This course is designed for students preparing for standard computer science exams, self-taught programmers looking to fill hardware knowledge gaps, and beginners with no prior hardware engineering experience.
