Show Answer With Best Explanation
Answer: ii
Explanation:
Prevention: Computer software deteriorates due to change, and because of this, preventive maintenance, often called software re-engineering, must be conducted to enable the software to serve the needs of its end users. In essence, preventive maintenance makes changes to computer programs so that they can be more easily corrected, adapted, and enhanced.
Enhancement/Perfective: As software is used, the customer/user will recognize additional functions that will provide benefit. Perfective maintenance extends the software beyond its original functional requirements.
Adaptation: Over time, the original environment (e.g., CPU, operating system, business rules, external product characteristics) for which the software was developed is likely to change. Adaptive maintenance results in modifications to the software to accommodate changes to its external environment.
Correction: Even with the best quality assurance activities, it is likely that the customer will uncover defects in the software. Corrective maintenance changes the software to correct defects.

Maintenance: Maintenance can be referred as a process of enhancement in the software product according to the changing requirements of users.
4 types of maintenance:
1- Preventive – increasing software maintainability or reliability to prevent
problems in the future.
2- Corrective – diagnosing and fixing errors, possibly ones found by users.
3- Perfective – implementing new or changed user requirements which concern functional enhancements to the software
4- Adaptive – modifying the system to cope with changes in the software environment .
