GUI feature the following basic components
- Pointer: A symbol that appears as a small arrow on the display screen and that you move to select objects and commands.
- 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.
- 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.
- Menus: Most graphical user interfaces let you execute commands by selecting a choice from a menu.
