- Kernel manages the CPU, Memory and Peripheral Devices of the PC.
- Graphical Server is often called the X Server, and manages the graphics on the screen.
- Daemons manage printing, scheduling , sound etc. (background services)
- Init System controls the Daemons and bootstraps the User Space, after the initial booting by the Bootloader.
- Desktop Environment interfaces with the actual User, and contains built-in applications such as web browsers, file managers, configuration tools etc. Examples are GNOME, Enlightenment, KDE etc.
