Introduction: Plug-in architecture is a design pattern that enables the development of software systems that can be extended and customized through the use of external components, known as plug-ins. This approach provides a number of benefits, including increased modularity, improved extensibility, and the ability to easily add new functionality to an application without having to modify its core code. Benefits of Plug-in Architecture: Modularity : Plug-in architecture allows software systems to be divided into smaller, more manageable components, making it easier to understand, develop, and maintain the code. Extensibility : Plug-in architecture makes it easy to add new functionality to a software system, as plug-ins can be developed and deployed independently of the main application. Flexibility : Plug-in architecture provides a great deal of flexibility, as it allows developers to add or remove functionality from an application as needed, without having to modify the core code.
