Introduction / Context:
Utilities are support programs that assist with development, maintenance, and operation—examples include editors, debuggers, file tools, and spoolers. The question asks which listed item is not a utility.
Given Data / Assumptions:
- Debugger: diagnostic tool aiding program testing.
- Editor: text/code editing tool.
- Spooler: manages print/IO spooling, a system utility service.
Concept / Approach:
- Each listed program type fits the general definition of a utility.
- Therefore, none of them is “not a utility”.
Step-by-Step Solution:
Evaluate each option against utility definition.Debugger → utility; Editor → utility; Spooler → system utility.Hence the correct choice is “None of the above”.
Verification / Alternative check:
OS distributions and IDE suites categorize these components under tools/utilities.
Why Other Options Are Wrong:
- Debugger/Editor/Spooler: All are utilities; selecting any would contradict standard classification.
- All of the above: Would imply none are utilities, which is false.
Common Pitfalls:
- Confusing “application” with “utility”—some editors are general-purpose apps but still function as utilities.
Final Answer:
None of the above
