GUI

Graphical User Interface

There are usually 3 levels of user interface..

Terminal: which is typically the white text on black background like on your first computer. If you're in X windows, you can see an x terminal by trying:

$ xterm ncurses: Not really a gui, but a prettier way to use terminals. If you're in a terminal and have dialog installed:

$ dialog --yesno "Is this site helpful?" 7 60

and then the GUI, which is typically a window where you will use your mouse to point and click instead of typing. In UBOs, the GUI is most often found in XFree86 and X.org.
