what is a GUI
- A GUI is a graphical display in one or more windows containing controls, called components, that enable a user to perform interactive tasks.
- Graphical user interface is sometimes shortened to GUI. The user chooses an option usually by pointing a mouse at an icon representing that option.
- Stands for "Graphical User Interface," and is pronounced "gooey." It refers to the graphical interface of a computer that allows users to click and drag objects with a mouse instead of entering text at a command line. Two of the most popular operating systems, Windows and the Mac OS, are GUI-based
i.e. windows 7,
the mac OS IOS 7
