Computer Organization and Architecture: Foundations and Exam Prep

Understanding how hardware interacts with software is essential for any aspiring computer scientist or exam candidate. This written course demystifies the inner workings of computer systems, bridging the gap between high-level programming and physical circuitry. Through structured written lessons, clear step-by-step numerical examples, and targeted practice problems, you will develop a deep mental model of computer architecture. You will gain the confidence to solve complex engineering and exam-level questions on processor design, memory management, and data representation. What you'll learn: Understand basic computer arithmetic, data representation, and floating-point standards; Analyze instruction set architectures (ISA), including modern RISC-V design principles and addressing modes; Evaluate CPU control unit design, pipelining stages, and techniques for resolving data hazards; Optimize memory hierarchy performance by mastering cache mapping, virtual memory, and replacement policies; Solve complex numerical problems related to execution time, speedup, and input/output data transfer; Explore contemporary multi-core processor concepts and cache coherence protocols. The course begins with fundamental terminology and representation formats before advancing to core hardware components, pipelining, and memory design. You will progress through detailed written explanations and comprehensive practice exercises designed to reinforce your analytical skills. This course is designed for computer science students, exam candidates, and self-taught developers seeking a solid hardware foundation. No prior hardware engineering experience is required to begin.
