**Includes services or DAEMONS
Device Drivers - ✔️✔️Interface b/w OS and hardware.
Shell - ✔️✔️Interface for user, often personalized. The shell provides access to the
kernel.
I.E. The GUI will translate mouse motions into calls to kernel/routines. Desktop
elements include shortcuts, windows theme, menus, background.
Services (Daemons) - ✔️✔️OS programs that start when OS is loaded. They run in the
background and wait for an event to initiate.
