A lightweight software component written in a cross-platform programming language like Java, JavaScript or Visual Basic. Applets are designed to be easily integrated into web pages and executed within a user’s web browser environment. When an HTML page containing an embedded applet is loaded, the browser retrieves and runs the compact program on the client-side to enable interactive web-based features and functionality.
Applets operate within a restricted sandbox environment that limits their system access privileges as a security measure. This constrained execution prevents applets from autonomously interacting with the host computer’s resources like files or hardware without explicit user consent. While convenient for enhancing web experiences, applets potentially expose risks if browser controls fail to properly confine their operations within the intended boundaries. Careful management of applet permissions is necessary to mitigate abuse.
