Every operating system concept in one video…

Fireship

Resumen

This video provides a deep dive into the architectural mechanics of an operating system, explaining what happens from the moment you press the power button to the final system shutdown. It covers fundamental concepts like bootloaders, privilege rings, virtual memory, file systems, device drivers, and process management. By peeling back the layers of abstraction, the video clarifies how software, hardware, and the kernel interact to make modern computing possible, illustrating the complexity of managing resources like CPU time and memory safely.

But right now, you're watching this video because one, God put at least one eyeball in your head, and two, because an operating system decided you could. It might be macOS if you're rich, Windows if you've given up on life, or Linux if you're part of the 3% of base gigachads out there. Either way, your CPU is running something like 400 other programs, and Chrome is eating 20 GB of RAM for no reason, and somehow your cursor still moves when you wiggle the mouse. This is not normal. It's a miracle performed thousands of times per second by the most underappreciated software ever written, the operating system. The first one, GM-NAAIO, was shipped in 1956 at General Motors because an engineer decided humanity had better things to do than hand-feed punch cards into a two-story IBM mainframe. It could run exactly one program at a time, had no memory protection, no users, no files, and it still…
