The Graphical Version Of Ms Dos Computer Science Essay

The Microsoft operating system has seen many alterations from past three decennaries. From Microsofts phonograph record runing system introduced in 1981 to windows 8 introduced in 2012, Microsoft runing system got changed wholly. What began as a difficult to utilize and understand text merely runing system with MS-DOS, it excogitate into a complete graphical user-friendly interface ( GUI ) with windows 8.
