Applet

An applet is an embedded program on a web site.

It is a software component that runs in the context of another program, for example a web browser. An applet usually performs a very narrow function that has no independent use. Hence, it is an application.

The term was first used in AppleScript in 1993, but predates that by nearly a decade.

Applets are usually written in the coding language called Java. They are normally used for creating a virtual object that may move or interact with the web site.
