User-interface dialogue techniques for terminal-based systems typically include structured interactions such as Q&A, forms, and menus. Which of the following is NOT considered a standard terminal dialogue technique?
-
AQuestions and answers
-
BOpen-ended questions
-
CForm fillings
-
DMenu display
-
ENone of the above
Answer
Correct Answer: Open-ended questions
Explanation
Introduction / Context: Classic terminal UIs favor constrained interactions that are easy to parse and validate, such as forms and menus. Open-ended prompts are less deterministic and harder to process.
Given Data / Assumptions:
- Terminal context with keyboard input and limited graphics.
- Need for predictable parsing and validation.
- Desire to minimize user errors.
Concept / Approach: Structured dialogues—menus, forms, and controlled Q&A—reduce ambiguity. Open-ended questions (free text essays) are atypical in such systems because they require complex parsing and offer inconsistent data quality.
Step-by-Step Solution:
1) Identify common terminal patterns: menus, form fields, yes/no prompts.2) Contrast with open-ended, unconstrained responses.3) Select the item that does not fit structured terminal dialogue.Verification / Alternative check: Examine classic CLI installers and admin tools; they rely on lists and forms, not essays.
Why Other Options Are Wrong:
Questions and answers in constrained form are standard.Form filling is a hallmark of data entry terminals.Menu display is the most common selection mechanism.“None of the above” is wrong because one item (open-ended questions) is indeed not standard.Common Pitfalls: Confusing open-ended with multi-line text fields in forms (which are still structured).
Final Answer: Open-ended questions.
