An operating system (OS) is a software program that explains user instructions to the computer and acts as an intermediary between the user and the computer hardware. Without the operating system, your device is useless because you can't perform anything on your computer. The operating system handles software and hardware.
Some examples of operating systems
- Windows operating system
- Kali Linux operating system
- Google Android operating system
- Mac operating system
- Chromium operating system

Graphical server: Graphical server also know as the X server. It displays a graphical user interface in your system.
Kernel: Kernel is the core of the operating system also call it the heart of an operating system. It works like a bridge between system hardware and software. Kernel manages communication between (software) user-level applications and hardware. It loads first in your operating system when your OS starts. Kernel decides who will use this resource.
Shell: Shell is a special program and provides an interface to use the OS services. Shell is a command intercepter. It fetches a command from the user and executes the command.
Desktop environment: The Desktop environment is a collection of software. It decides how your desktop looks and works. It includes built-in applications such as file manager, text editor, image viewer, etc.
