MDI refers to which type of interface?

• A. Menu Driven Interface
• B. Multitasking Debug Interface
• C. Machine Direct Input
• D. Managed Data Interface

Answer: (A)

A Menu Driven Interface presents the user with a set of menus and choices, guiding interaction through selections rather than free text or direct hardware commands. You navigate by choosing items from displayed menus, often using numbers or arrows to move through options. This approach is easy to learn, reduces the chance of input errors, and is well suited for systems with limited input methods or when tasks follow a predictable, step-by-step flow. The other descriptions refer to different ideas—debugging multiple tasks, direct low-level input from hardware, or a data-handling layer—none of which describe interacting through a menu of selectable options. Therefore, the menu-driven approach best matches the meaning of this interface in this context.
