What is the a client server on X window system?

In the X Window System, a client-server model is used where the client is typically a graphical application that requests services, such as rendering graphics or handling user input, while the server is the X server that manages the display, keyboard, and mouse. The X server listens for requests from multiple clients, allowing them to draw Windows, handle events, and interact with the user interface. This architecture enables applications to run on one machine while displaying their output on another, facilitating remote graphical sessions.
