What term refers to changes to software performed to fix bugs, improve performance, or adapt to new environments?

• A. Upgrade
• B. Patch
• C. Maintenance
• D. Deployment

Answer: (C)

Maintenance is the umbrella term for the ongoing changes made to software to fix defects, improve efficiency, and ensure it runs well in new environments. It covers bug fixes, performance improvements, and updates needed for compatibility or security. A patch is a small, targeted fix for a specific problem and is just one type of maintenance activity. An upgrade means moving to a newer version with new features, not the broad set of ongoing fixes and tweaks described here. Deployment is the act of releasing the software to users, not the changes themselves.
