Advantages of GUIs

An advantage of GUIs is that they make computer operation more effective and friendly so it is easier to learn and use. It is much easier for a new user to move a file from one directory to another by dragging its icon with the mouse.

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.
