The operating system runs its processes in two distinct modes: User and Kernel.

Here's a step-by-step explanation:

1. User Mode: In this mode, the executing code has no ability to directly access hardware or reference memory. The code can only access a small subset of instructions and a limited amount of memory. This mode is designed for applications and user interface.

2. Kernel Mode: In this mode, the executing code has complete and unrestricted access to the underlying hardware. It can execute any CPU instruction and reference any memory address. Kernel mode is generally reserved for the lowest-level, most trusted functions of the operating system.

So, the operating system switches between these two modes depending on what type of code is being executed.
