Architecture of Windows OS

The architecture of Windows OS is a layered design that consists of two main components: user mode and kernel mode.

  • User mode: User mode is where applications run and interact with the Windows API, which provides services for graphical user interface, system resources, networking, audio and more. Kernel mode is where the core components of the operating system reside, such as the kernel, drivers, security manager and hardware abstraction layer.
  • Kernel Mode: The kernel is responsible for managing processes, threads, memory, I/O and security. Processes are containers for executing programs, which consist of code and data. Threads are units of execution within a process that carry out the instructions of the program. Each process has at least one thread, but can have multiple threads to perform concurrent tasks. The Windows OS supports different types of processes and threads depending on their functionality and requirements.

How does Windows OS Works

Windows OS is an operating system designed by Microsoft that allows you to use a computer. An operating system is the core set of software that manages all of the hardware and software resources on the computer. Windows OS handles multi-tasking, allocating hardware resources among multiple running programs, and controlling which processes run on different CPUs or cores.

Windows OS also provides the tools and interfaces for you to browse the Internet, check your email, edit digital photos, listen to music, play games, and do much more. Windows OS comes preloaded on most new personal computers (PCs), which makes it the most popular operating system in the world. There have been many versions of Windows OS since its first release in 1985, but the most recent one is Windows 10.
