What is the difference between preventive maintenance and corrective maintenance?

Explanation:
Preventive maintenance is planned and scheduled to prevent failures before they happen. It involves regular inspections, servicing, lubrication, adjustments, and component replacements based on time or usage intervals to keep systems reliable and safe. Corrective maintenance, on the other hand, is performed after a fault or failure is detected, with the goal of restoring functionality through troubleshooting, repair, or part replacement as needed. The difference lies in timing and purpose: preventive is proactive and aimed at preventing downtime, while corrective is reactive and aimed at fixing something that has already failed.
