Plug-ins
Plug-ins are programs that are installed in your browser that enable it to play various types of media, such as video. Examples of plug-ins include Quicktime Player and Flash Player. If you don't have the correct plug-in, the site will usually provide a link to download the plug-in.
Once you have the necessary plug-ins, you'll be able to enjoy streaming video from sites such as Hulu, and play games on sites such as Newgrounds.

Your browser may have come with some plug-ins already installed.
