Learn more about Linux runlevels — the right way!

You can think of Linux runlevels as different "modes" that the operating system runs in. Each of these modes, or runlevels, has its own list of processes and services that are either turned on or off. From the time Linux boots up, it’s always in some runlevel.

This runlevel may change as you continue to use your computer, depending on what kind of services the operating system needs access to.
