 (That would be a big waste of resources!)
 Instead, each qube represents a [security domain] (e.g., "work," "personal," and "banking").
 By default, all qubes are based on a single, common [template], although you can create more templates if you wish. 
-When you create a new qube, you don't copy the whole root filesystem needed for this qube to work (which would include copying all the programs). 
-Instead, each qube *shares* the root filesystem with its respective template. 
-A qube has read-only access to the filesystem of the template on which it's based, so a qube cannot modify a template in any way.

 This is important, as it means that if a qube is ever compromised, the template on which it's based (and any other qubes based on that template) will still be safe. 
 So, creating a large number of qubes is cheap: each one needs only as much disk space as is necessary to store its private files (e.g., the "home" folder).

 Each qube, apart from having a distinct name, is also assigned a **label**, which is one of several predefined colors.
 The trusted window manager uses these colors in order to draw colored borders around the windows of applications running in each qube.
