A GUI makes use of a WIMP environment:
This type of interface is user-friendly; the system functions are accessed by selecting icons and items from pull down menus.
Icons are pictures representing programs, files and folders. Double clicking an icon opens a window that contains programs, folders and documents. When you are in a folder, you can launch a program or document by double clicking the icon or you can drag it to another location.
The pull down menu is a list of options that appear below a menu bar when the user clicks on it.
The pointeris the arrow controlled by the mouse which lets you choose options from menus.
The background screen that displays icons, files and folders is called the desktop.
