DEFINITION AND BASIC COMPONENTS
Abbreviated
GUI (pronounced
GOO-ee). A
program interface that takes advantage of the
computer's graphics capabilities to make the program easier to use. Well-designed graphical user interfaces can free the user from learning complex
command languages. On the other hand, many
users find that they work more effectively with a
command-driven interface, especially if they already know the command language.
Graphical user interfaces, such as
Microsoft Windows and the one used by the
Apple Macintosh, feature the following basic components:
pointer : A symbol that appears on the display screen and that you move to select objects and commands. Usually, the pointer appears as a small angled arrow. Text -processing applications, however, use an I-beam pointer that is shaped like a capital I.
pointing device : A device, such as a mouse or trackball, that enables you to select objects on the display screen.
icons : Small pictures that represent commands, files, or windows. By moving the pointer to the icon and pressing a mouse button, you can execute a command or convert the icon into a window. You can also move the icons around the display screen as if they were real objects on your desk.
desktop : The area on the display screen where icons are grouped is often referred to as the desktop because the icons are intended to represent real objects on a real desktop.
windows: You can divide the screen into different areas. In each window, you can run a different program or display a different file. You can move windows around the display screen, and change their shape and size at will.
menus : Most graphical user interfaces let you execute commands by selecting a choice from a menu.
