MS-DOS was the Microsoft-marketed version of the first operating system to be widely installed on personal computers (PCs). It was essentially the same OS that Bill Gate's young company developed for IBM as Personal Computer - Disk Operating System (PC-DOS).. Donald A. Dornbusch. 1. , Yi Lin. 2. , Rocco P.
