How windows Works & Architecture?

Windows Architecture:

Windows uses a layered architecture, meaning that it is divided into different layers, each of which has a specific function. This makes it more modular and easier to maintain. The two main layers in Windows are:

User mode: This layer contains all of the programs and services that you use on a daily basis, such as web browsers, word processors, and games. User-mode programs have limited access to system resources and must interact with the kernel mode through system calls.

Kernel mode: This layer is responsible for managing the hardware and system resources of the computer. It also provides services to user-mode programs, such as memory management, file system access, and networking. Kernel-mode programs have full access to system resources and can run at any time.

How Windows OS Works:

When you turn on your computer, the BIOS (Basic Input/Output System) loads the Windows bootloader. The bootloader then loads the Windows kernel into memory. The kernel then initializes the hardware and system resources, and then loads the user-mode programs that you have configured to start up automatically.

Once the kernel is running, it manages the execution of all of the programs on your computer. It does this by scheduling each program to run for a short period of time, and then switching to the next program in the queue. This process is known as context switching.

The kernel also provides services to user-mode programs, such as memory management, file system access, and networking. User-mode programs can request these services by making system calls.
