Which statement correctly describes Disk Operating System in the material?

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

Answer: (A)

Disk Operating System is the software that manages disk drives and basic computer operations, such as the file system and boot process, typically accessed via a command-line interface. The material uses this term to describe the system responsible for disk operations, so naming it Disk Operating System best matches the description. The other options refer to different concepts: a Graphical User Interface is the visual way users interact with software, not the core OS itself; a Real-Time Operating System is built to handle tasks with strict timing requirements; a Mobile Operating System is designed for phones and tablets.
