Applet

An applet is a small software program designed to run within a web browser or an application, enabling it to perform specific functions without needing to be a full standalone application. Typically written in Java or similar languages, applets can add interactivity, display dynamic content, or process user input directly on webpages. They are embedded into webpages, allowing users to experience features like games, interactive forms, or visualizations seamlessly within their browser environment. Despite decreasing popularity with modern web development, applets historically facilitated rich, portable functionality across different systems.
