| Short for
Graphical User Interface, the GUI was first developed at Xerox
PARC by Alan Kay, Douglas
Engelbart, and a group of other researchers. A GUI uses
windows, icons, and
menus to carry out commands
such as opening files, deleting files, moving files, etc. and although
many GUI Operating Systems are operated by using a mouse,
the keyboard can also be used by using keyboard
shortcuts or arrow keys.
Unlike a command line
Operating System like Unix or MS-DOS,
GUI Operating Systems are much easier for end-users to learn and use
because commands do not need to be known or memorized. Because of
their ease of use, GUI Operating Systems have become the dominant
Operating System used by end-users today.
A few examples of a GUI Operating Systems:
- Microsoft Windows 95
- Apple System 7
- Apple Mac OS.
A few examples of a GUI interfaces are:
- GNOME
- KDE
