Maintenance, in the context of software or systems, refers to the ongoing activities that ensure a product remains in good working condition, performs as expected, and adapts to changing needs. There are different types of maintenance, including corrective, adaptive, perfective, and preventive maintenance.
Corrective maintenance involves addressing and fixing defects or issues that arise during the use of software or systems. Adaptive maintenance is concerned with modifying software to accommodate changes in the environment or requirements. Perfective maintenance aims to improve software performance, efficiency, and user experience. Preventive maintenance proactively reduces the likelihood of future problems.
Maintenance is crucial to the longevity and effectiveness of software and systems. For example, regular software updates and security patches are a form of maintenance that helps keep software secure and functional.
