Jack Panel

   The Jack Panel is the group of connection jacks, or plugs, on the back of audio/video components. Sometimes jacks will be on the side or front of a component. This is where the components are connected.

   On video components the jacks can include different types of video jacks (composite, component, S-video, DVI, HDMI, etc.) and audio jacks. The number and types of jacks that are on the component determine what you can connect to the component.
