Back when I was using a 80386 PC in the 1990s, I would start up my pc and the first thing that would happen was that a black screen with a C:> single command prompt would appear. Most of the time, I would then just punch in the following command against the prompt:
This command would boot up Windows 3, a graphical user interface for your PC. More and more applications were migrating to this platform, rather than being started up stand alone from the C:> command prompt. In 1995, Microsoft released Windows 95, marking the end of the C:> command prompt as the base platform. The base had platform shifted to the graphical user interface.
These days, the first thing I do when I start up my Windows XP PC is to start my Firefox browser. From here I can access my email on GMail and connect with my friends on Facebook. I have even started editing my documents online using Google Docs. I can see the end is near for the graphical user interface we call 'the desktop'. The platform is about to move again to the Web.
