Foundations of Computer Architecture and System Programming

Have you ever wondered what happens under the hood when your code executes? To build robust, high-performance software, you must understand the fundamental relationship between hardware and operating systems. This text-only course delivers a clear, comprehensive introduction to computer architecture and system-level programming. You will trace the journey of data from physical transistors up to modern operating system kernels, establishing a rock-solid mental model of computing. What you'll learn: 1. Understand the core components of computer hardware, including the CPU, registers, and buses. 2. Learn how numbers, text, and instructions are represented and processed at the machine level. 3. Master the essentials of memory management, virtual memory, and caching strategies. 4. Explore how operating systems manage processes, threads, and system calls. 5. Analyze how high-level programming languages translate into low-level machine code. 6. Practice thinking like a systems programmer to write more efficient and hardware-aware code. The course begins with essential terminology and the historical evolution of computing systems, then progresses step-by-step through CPU architecture, memory hierarchies, and operating system fundamentals. This course is designed for absolute beginners, self-taught programmers, and computer science students looking for a clear, conceptual guide. No prior hardware engineering or low-level programming experience is required. Start reading today to master the core principles of computer systems and elevate your programming skills.
