Guess What? DOS turns 30. DOS stands Disk Operating System and the MS in MS-DOS stands for Microsoft. It is one of the oldest operating system that was used widely a decade ago. This operating system as I remember was the first thing which was taught in my primaries along with a language like GW-BASIC not sure. The last operating system to use DOS startup disks was Windows XP. Games like WOLF 3D originated from DOS.
The latest commercial product in DOS is DOS 6.22
Decades Later we still find it on Windows. To access it go to run-> and type cmd.
