The X Window System, commonly referred to as X or X11, is a computer software system and network protocol that provides a graphical user interface (GUI) for networked computers. Developed at the Massachusetts Institute of Technology (MIT) in the 1980s, X Window System is widely used in Unix-like operating systems, including Linux and many other Unix-based systems.
X Window System allows for the display of graphical elements such as windows, icons, buttons, and menus on a computer screen, and it provides mechanisms for user input through keyboard and mouse. It uses a client-server model, where the X server runs on the computer that is connected to the display and manages the display hardware, while X clients run on other computers and communicate with the X server over a network to request graphical rendering and user input.
X Window System is used by desktop users who run Unix-like operating systems, such as Linux, BSD, and other Unix-based systems. It provides a graphical user interface (GUI) for desktop environments like GNOME, KDE,
