Computer Architecture Fundamentals: From Hardware to Operating Systems

Ever wondered what actually happens inside a computer when your code runs? Understanding the bridge between physical hardware and software execution is the key to becoming a truly versatile programmer or systems engineer. This text-based course guides you from the absolute basics of binary logic up to the complex orchestration of modern operating systems. You will gain a clear mental model of how processors execute instructions, how memory is managed, and how operating systems coordinate multiple tasks simultaneously, preparing you to write more efficient and optimized code. What you'll learn: Understand foundational digital logic, binary representations, and information encoding; Explore processor architecture, the instruction cycle, and the key differences between modern x86 and ARM designs; Analyze memory hierarchies, including registers, cache levels, RAM, and virtual memory; Read and interpret basic assembly language instructions to see how code runs at the hardware level; Examine operating system core functions, multitasking, and inter-process communication; Learn the basics of network protocols and how peripheral devices communicate with the CPU. The course begins with core terminology and binary math, gradually moving through physical processor components, assembly language, and operating system internals. You will read structured explanations and analyze real-world architectural patterns to solidify your understanding. This course is designed for beginner programmers, computer science students, and tech enthusiasts with no prior hardware background.
