Now for something a little bit different. X11 is not a program that does anything by itself; by installing it it allows you to run other programs. But no, it has nothing to do with running MS Windows or Windows programs on your computer.
From Apple's website:
X11 for Mac OS X is an implementation of the X Window System that makes it possible to run X11-based applications in Mac OS X. Based on the X.org Foundation releases -- the leading reference implementation of X11 -- X11 for Mac OS X is compatible, fast, and fully integrated with Mac OS X. It features includes full X11R7 compatibility including an X window server, Quartz window manager, libraries, and basic utilities such as xterm. It is optional but installed by default on Mac OS X v10.5 Leopard. The X11 SDK headers are available as part of the Xcode Developer Tools.
Why X11? In the future, I will recommend some open source programs that require X11. Occasionally, not too often.
X11 should be included on your OS X Install Disks. Or, get it here.
