What is Microsoft Windows:

Microsoft Windows or better known as Windows is a family of operating systems developed by Microsoft, using a graphical user interface (GUI).

The Windows operating system has evolved from MS-DOS, an operating system based on text mode and command-line. The first Windows version, Windows Graphic Environment 1.0 was first introduced on November 10, 1983, but it just came out in November 1985 created to cater for the needs of the computer with a display.

Windows 1.0 is an additional 17-bit software (not an operating system) running on MS-DOS (and some variants from MS-DOS), so it will not work without the DOS operating system. Version 2.x and Version 3.x are also the same. Some recent versions of Windows (starting with version 4.0 and Windows NT 3.1) are free operating systems that are no longer dependent on MS-DOS operating systems. Microsoft Windows can then expand and master the operating system up to 90%.


OPERATING SYSTEM is a system software that manages resources from hardware and software. Without an operating system, users can not run application programs on the computer.

Operating systems have systematic scheduling including calculation of memory usage, data processing, data storage and other resources.

For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between the application program and the computer hardware, although the application code is usually executed directly by the hardware and all devices containing the computer.

Examples of modern operating systems are Linux, Android, iOS, Mac OS X and Microsoft Windows.


In computer technology, a graphical user interface or APG (Graphical User Interface or GUI) is a type of user interface that uses interaction methods on a graphical electronic device (not a text command) between the user and the computer.

The GUI is one of the ease factors in the use of computers, mobile devices such as MP3 players, portable media players or gaming devices. The GUI describes the information and commands available to the user using a graphical icon.

Example: Microsoft Windows, MacOS and Xwin use different GUI types.

MS-DOS | Abbreviated from Microsoft Disk Operating System, is an operating system that is widely used by IBM-PC or compatible computers. Microsoft created MS-DOS as a mainstream operating system, before eventually halting MS-DOS support slowly as they created a graphical interface operating system (also known as GUI) for the mainstream marketplace, called Microsoft Windows.

MS-DOS was first launched in 1981, and over time, Microsoft also launched a newer version of MS-DOS. Not least until Microsoft launched new versions of MS-DOS from 1981 until Microsoft stopped MS-DOS support in 2000.

MS-DOS is one of the key to Microsoft’s success in producing software from a small company of language makers when it was built to become a world-class device.
