OS Fundamentals — What Even Is an OS?
Starting with the basics — an OS is software, not hardware, and programs run through a Fetch → Decode → Execute cycle.
Computer systems topics like operating systems, memory, threads, scheduling, caches, and networking are often taught through dense lectures and abstract diagrams. These ideas are easier to understand when you can see what is happening step by step.
Just know that my long-term vision is that I'm building a tool in this space (I'm shooting for the stars with the focus/scope/customers/context, will reveal details when I'm ready), but for now, the current focus is my personal learning journey. This is where I document what I'm learning, create visual notes, and gradually build interactive explanations that make invisible systems feel more intuitive.
