    7. 7. PART 1: Operating SystemWhat is an Operating System?An operating system (OS) is a software program that controls andruns just about everything on your computer. Windows (98, 2000, XP)are all examples of different versions of the Windows OperatingSystem. The Windows OS has three main parts: Desktop, Taskbarand Start Button.Like a conductor or a coach -- an OS is an ‘invisible’ intermediary whomakes sure that all the different components (hardware and software)work smoothly together. Although there are many different kinds ofoperating systems, Windows is most commonly used on PCs.What makes Windows special?Windows makes computers easier to use because it employs a GUI(“gooey”) or Graphical User Interface. Instead of requiring users toremember specific commands, GUIs represent different tasks andfunctions with pictures. Now all a user needs to do is “point and click”.
