What is "applet"

Applet is a small software that performs a specific activity, within (the context) of another larger program (such as a web browser), usually as a Plugin. Unlike a program, an applet cannot run independently; an applet usually displays a graphical part and sometimes interacts with the user. However, they are usually stateless and have restricted security privileges. the applet must run in a container, which is provided by a host program, through a plugin, or a variety of other applications, including mobile devices that support the applet programming model.
