MS-DOS stands for which of the following?

MS-DOS stands for which of the following?

• A. Microsoft Disk Operating System
• B. Microsoft Data Operating System
• C. Microcomputer Disk Operating System
• D. Multi-Drive Operating System

Answer: (A)

You're being asked to identify what the acronym MS-DOS stands for. It refers to the historical operating system from Microsoft used on early IBM PC compatibles, and it stands for Microsoft Disk Operating System. The word "Disk" reflects its disk-based storage and command-line approach, which was central to how the system operated at the time. The other options don’t fit because they change the key term: “Data” would imply a data-centric name, “Microcomputer” isn’t the official naming, and “Multi-Drive” isn’t the term used for the product. (Note that IBM’s branded version was PC-DOS, essentially the same system.)
