You can download the most recent Netscape browser at the Netscape Download site. That's where plugins and helper applications come in handy. Plugins are mini applications that can be used by your browser to do a variety of things. They extend the browsers capabilities in a specific way - giving you, for example, the ability to play audio samples or view video movies from within the browser. For more information about plugins, check out Netscape's Plugin page .
Helper applications are external programs that the browser can call to perform a task.
These tasks may include playing of audio files, viewing a document, or even opening a chat connection so that the user may talk with other people over the Internet. Probably the most popular helper application is RealAudio . Many sports events are made available for listening through RealAudio. The creators of RealAudio have created another Real product, called RealVideo. RealVideo is similar to RealAudio, but it also allows video images to be played.
