Question

BlackTom AI · Accepted Answer

The question asks which type of maintenance involves altering an operating system to improve efficiency, reliability, and maintainability.

Option a: Preventive Maintenance — This focuses on preventing potential failures before they occur, often through scheduled tasks and housekeeping rather than enhancements to efficiency or maintainability. It’s about reducing the likelihood of defects, not about improving the system’s performance characteristics.

Option b: Perfective Maintenance — This explicitly aims to improve a system’s performance, reliability, or maintainability after it has been deployed. It encompasses changes that make the system more efficient, easier to maintain, or more reliable, aligning directly with the prompt.

Option c: Adaptive Maintenance — This involves modifying the system to operate in a new or changing environment (e.g., new hardware, new platforms, updated interfaces). It does not primarily target efficiency or maintainability improvements, but rather compatibility with external changes.

Option d: Corrective Maintenance — This is about fixing defects or faults discovered in the system to restore expected functionality. It addresses correctness and repair rather than proactive enhancements to performance or maintainability.

In summary, the description given in the prompt matches Perfective Maintenance because it centers on improving the system’s efficiency, reliability, and maintainability rather than preventing failures, adapting to environment changes, or correcting defects.
