History
MS-Windows is an operating system and programming environment that provides users a friendly graphical interface based on windows, media interaction and modern screen: menus, buttons, graphics cursor, "boxes" of dialogue and others. This explains the great popularity enjoyed, especially after his last versions. Windows had many additional features unlike DOS environment, it has standard graphical user interface, execution of simultaneous programs, computer hardware virtualization, resources to share with its many programs, opportunities for exchange of data between applications. Thus, a DOS program has exclusive access to internal memory, full screen console and equipment input / output. In Windows, all computer hardware resources are shared between programs that run simultaneously. A Windows program has access only to a physical area of the screen, which is the "window" of work. It is used not only for display but for any operation of user interaction. Windows programs can overlap and perform simultaneously on the screen surface; they can be resized and moved on the screen.
