Question

BlackTom AI · Accepted Answer

Utility programs are specialized software designed to maintain, manage, diagnose, or optimize a computer’s resources — for example, disk clean-up removes temporary files and reclaims storage space.

1) Relevant knowledge points and concepts
- System software: software that manages core computer functions (example: operating system).
- Application software: programs that perform user-level tasks (examples: word processors, spreadsheets).
- Utility programs: a category of system-support tools that perform maintenance/optimization tasks such as disk cleanup, disk defragmentation, antivirus scanning, backup, and file compression.

2) Step-by-step reasoning
Step 1: Identify the category for each option based on definitions above.
Step 2: Compare each option to the definition of a utility program (does it perform maintenance/management tasks for the system?).

3) Classification of each option (intermediate steps shown)
- a. Word processor — an application program used to create and edit documents (user-level productivity software). Not a utility.
- b. Spreadsheet — an application program for organizing and calculating tabular data (user-level productivity software). Not a utility.
- c. Disk clean-up — a maintenance tool that removes temporary files, clears caches, and reclaims disk space. This directly matches the utility program definition.
- d. Operating system — core system software that provides hardware management and platform services; it is not a utility (although it can include utilities).

4) Why the correct answer is correct
Disk clean-up is explicitly a utility because its purpose is to maintain and optimize the computer’s storage by deleting unnecessary files and freeing space. That maintenance/optimization role is the hallmark of utility software.

5) Why the other options are incorrect
- Word processor and spreadsheet are application software for creating documents and spreadsheets, not for system maintenance.
- Operating system is system software that provides the runtime environment and resource management; it is not classified as a utility (though it may contain utility programs).

6) Conclusion
Therefore the correct answer is c. Disk clean-up, which matches the provided answer.
