Introduction to Computer Architecture and Hardware Fundamentals

Ever wondered what actually happens under the hood when your code runs? Understanding the physical and logical structure of a computer is key to writing efficient software and troubleshooting complex system issues. This text-based course guides you through the core components of modern computer systems, from basic logic gates to complex processor architectures, without requiring any prior hardware background. In this course, you will learn to: Understand the fundamental roles of the CPU, GPU, motherboard, and system bus; Compare modern processor designs, including x86 and ARM architectures; Analyze the memory hierarchy, from high-speed CPU registers and caches to RAM and storage; Explain how input/output peripherals communicate with the core system; Explore how hardware virtualization features support modern cloud and container environments; Practice analyzing system performance and bottlenecks through written exercises. You will start with foundational terminology and hardware definitions, then progress step-by-step through processor operations, memory management, and peripheral communication. This course is perfect for beginners, self-taught programmers, and entry-level IT enthusiasts who want a solid grasp of hardware fundamentals. No prior engineering experience is required.
