X Window System Servers

X Window System servers run on computers with bitmap displays. The server distributes user input to and accepts output requests from various client programs through a variety of different interprocess communication channels. Although the most common case is for the client programs to be running on the same machine as the server, clients can be run transparently from other machines (including machines with different architectures and operating systems) as well. X supports overlapping hierarchical subwindows and text and graphics operations, on both monochrome and color displays.
The number of programs that use X is quite large. Programs provided in the core X.Org Foundation distribution include:
  1. a terminal emulator, xterm;
  2. a window manager, twm;
  3. a display manager, xdm;
