User Mode is a less privileged mode where most applications operate, creating a safer environment as it limits direct hardware access and interaction with system-level instructions. When an application requires to perform operations that demand direct hardware access, it makes calls to the underlying operating system code running in Kernel Mode.

Kernel Mode is the high privilege mode that has unrestricted access to the system memory and hardware. It is the operating layer where the kernel and device drivers run. The kernel is the central part of an operating system that manages operations of the computer and the hardware – mostly CPU, memory, and input/output devices. Device drivers are system-level software that helps the kernel handle hardware or abstract low-level hardware processing.

3.3. Transitions between User Mode and Kernel Mode

Transitions between User Mode and Kernel Mode are usually done through a programmed procedure called a context switch. A context switch is typically invoked when an operating process in User Mode makes system calls to Kernel Mode. Context switch time is pure overhead because the system is not performing useful work during this time. Therefore, the operating system, such as Windows, runs processes as long as possible in User Mode before transitioning into Kernel Mode, keeping context switch overhead to a minimum.
