Window Switch is a tool which allows you to display running applications on other computers than the one you start them on. Once an application has been started via a winswitch server, it can be displayed on other machines running winswitch client, as required.
You no longer need to save and send documents to move them around, simply move the view of the application to the machine where you need to access it.

The X Window System is a networked display system. A server component, the X server, is responsible for coordinating between all of the clients connected, taking input from the mouse and keyboard, and pushing pixels on the output. The most popular X server implementation is the Xorg X server, developed by the X.Org Foundation and community. There are other X server implementations: you might remember that Xorg was forked from XFree86 a decade ago, that Sun Microsystems has had several X server implementations, in both Xsun and XNeWS. Today, Xorg is the dominant X server implementation, getting most of the development. But back in the day, multiple competing implementations existed.
