Computer Engineering Foundations: Architecture and Operating Systems

Every developer writes code, but understanding how that code actually interacts with physical hardware and the operating system is what separates great developers from the rest. This text-based course bridges the gap between high-level programming and low-level execution, giving you the mental models needed to write highly optimized, resource-efficient software. What you'll learn: • Understand core computer architecture principles, including CPU registers, cache hierarchies, and memory addressing. • Learn how operating systems manage processes, threads, and system resources. • Explore the differences between modern CPU architectures like x86 and ARM. • Master the fundamentals of memory management, virtual memory, and page tables. • Analyze how input/output operations and file systems interact with hardware. • Practice optimizing code performance by aligning with hardware and OS execution patterns. You will start with foundational concepts of binary representation and basic digital logic, progress through processor design and memory hierarchies, and finish with operating system kernel tasks like scheduling and concurrency. This course is designed for self-taught developers, bootcamp graduates, or anyone looking to build a rigorous computer science foundation from scratch without complex prerequisites. Start reading today to unlock a deeper understanding of the machines that run your code.
