In monolithic operating systems like Gaia, system calls are initiated from User Mode to request services or functions that require kernel-level privileges.
- User Mode is where applications and processes run with limited privileges. When these applications need to perform a system-level function (e.g., accessing hardware, managing memory, or interacting with the file system), they make a system call to transition into Kernel Mode.
- The Kernel Mode is where the operating system's core functions are executed with full privileges.
