Computer Architecture Fundamentals: How Hardware Works

Ever wondered how software instructions translate into physical actions inside a machine? Understanding the hardware layer is the key to writing optimized code and mastering system design. This text-based course guides you through the foundational principles of computer architecture, taking you from basic number systems and Boolean algebra to the intricate design of central processing units and modern memory systems. What you'll learn: - Understand binary arithmetic, hexadecimal representation, and how data is stored in hardware. - Analyze Boolean logic, logic gates, and how they combine to form complex arithmetic units. - Explore CPU design, instruction set architectures, and the classic fetch-decode-execute cycle. - Examine modern performance-boosting techniques including pipelining, cache hierarchies, and parallel processing. - Compare different architecture paradigms such as CISC, RISC, and the open-standard RISC-V. - Practice hardware-level thinking through written exercises and step-by-step logic tracing. You will start with the absolute basics of data representation and logic gates before progressing to processor organization, memory management, and modern execution techniques. This course is designed for aspiring software engineers, computer science students, and curious beginners who want to build a rock-solid mental model of hardware with no prior engineering experience required.
