Using the Computer and Managing Files: Chap1-Less3

INTRODUCING THE COMPONENTS OF GUI

GUI = Graphical User Interface
All applications have a user interface that functions as a link between the computer and the user.
The GUI interface is also referred to as the GUI environment.
The GUI environment uses illustrations rather than text so that the user can interact with an application easily.
You can use the mouse to work with different applications in the GUI environment.
Microsoft has developed various operating systems in a GUI environment, Windows 95, Windows XP, Windows Vista, Windows 7, etc.

   Basic Elements of a GUI

A GUI interface consists of certain basic elements. These elements can be categorized as the following:
 Icons
 Window
 Menu
 Dialog box
 Property Sheet


Icons
Icons are pictorial representation of an object on the screen, which initiates a specific action when clicked.
There are basically many different icons displayed on your desktop. These icons enable navigation to various locations, such as disk drives, files, and folders.
