Describe the sequence of steps for loading a Linux server, from power on to full system readiness.

Linux server boot sequence:

1. BIOS/UEFI — performs hardware self-test (POST) and device initialization upon power-on.
2. Bootloader — for example, GRUB. It loads the Linux kernel into memory.
3. Linux Kernel — initializes hardware, mounts the root filesystem, and starts the init process.
4. Init system — launches system services and daemons. In modern distributions, this is systemd; in older ones, it is SysVinit or Upstart.
5. Starting services and user processes — network services, ssh daemon, task scheduler, etc.
6. System readiness — the server is available for users and applications.

Each stage is critical for the successful boot and startup of the system.
