Graphical User Interface

With a Graphical User Interface (GUI) almost all operations can be carried out by using a mouse to select commands from menus or click icons on the screen.

Parameters and switches are replaced by dialogue boxes – pop-up windows containing controls, eg:

  • check boxes: similar to switches. When the box is checked, the switch is on, when unchecked the switch is off
  • radio buttons provide a set of options, only one of which can be “on” at any time
  • list boxes: lists of parameters, from which one can be selected
  • edit boxes: boxes that allow parameters to be typed in
  • buttons: used to select further options or dialogue boxes.

A listing of the contents of the C:\Windows directory would be similar to the following:
