Which item is an example of a utility function?

• A. Word processor
• B. Disk cleanup utility
• C. Spreadsheet
• D. Web browser

Answer: (B)

A utility program is software that performs a specific maintenance or support task for the computer, rather than creating content or providing end-user workflows. Disk cleanup fits this idea because it scans for and removes unnecessary files, caches, and old data to reclaim disk space and help the system run more smoothly. The other items—word processor, spreadsheet, and web browser—are all application software designed for creating or accessing content and completing typical end-user tasks, not for maintaining the system. So the disk cleanup utility is the example of a utility function.
