Windows 3.1 is an operating system that was developed by Microsoft for IBM type computers. Windows 3.1 provides the user with a GUI environment. GUI is graphical user interface and this means there are point and click options available with which to work on the computer. We use the mouse to point and click on an icon to open program groups, launch programs and complete other tasks. The icons in Windows 3.1 are the small picture representations of a "doorway" to a task or program. The advantages of having a graphical user interface are obvious, it is much easier to move the pointer with the mouse and then click to do what we want with the computer than to remember obscure and sometimes complicated commands. Windows 3.1 gives you, the user a file management program called (with the usual brilliance and imagination of computer scientists) file manager, that is easy to understand and use. Windows 3.1 requires MS-DOS for installation. The main program in Windows 3.1 is Program Manager. If you close Program Manager, you close Windows 3.1.
