Fireship

A broad overview of how operating systems work, covering every major concept from boot to shutdown. Topics include the bootloader (UEFI/BIOS, GRUB), CPU privilege rings (ring 0 vs ring 3), virtual memory and the MMU/page tables, file systems and inodes, device drivers and hardware interrupts, process creation (PID1/systemd), system calls, the CPU scheduler, threads and race conditions, and interprocess communication (pipes, sockets). The shutdown sequence (SIGTERM, SIGKILL, filesystem unmount) is also explained.
