Which term is described as text-based and is commonly abbreviated as the Disk Operating System?

• A. Disk Operating System
• B. Graphical User Interface
• C. Real-Time Operating System
• D. Mobile Operating System

Answer: (A)

Text-based environments use a command-line interface where you type instructions rather than clicking icons. Disk Operating System is the traditional term for such systems, and it’s abbreviated as DOS. In DOS, interaction happens through typed commands and a text prompt (like C:\>), not through graphical menus. This contrasts with options that describe graphical interfaces, real-time or mobile operating systems, which are not defined by being text-based. So the term that fits the description is Disk Operating System, commonly abbreviated as DOS.
