X Window System

• X is the window system of Unix
• X inverts the client/server model: a client is an application, the server is a graphics server with a user
• A client prepares a graphics message such as CreateWindow
• The server is repsonsible for creating and drawing the window
• User events such as key presses are sent from the graphics server to application client
