Connector Description
Audio line-in connector
Used to receive audio signals from an external audio device, such as a stereo
system. When you attach an external audio device, a cable is connected between
the audio line-out connector of the device and the audio line-in connector of the
computer.
Audio line-out connector
Used to send audio signals from the computer to external devices, such as powered
stereo speakers (speakers with built-in amplifiers), headphones, multimedia
keyboards, or the audio line-in connector on a stereo system or other external
recording device.
DisplayPort connector
Used to attach a high-performance monitor, a direct-drive monitor, or other devices
that use a DisplayPort connector.
Note: The DisplayPort connector is not applicable on some models. If your
computer has a graphics card installed, be sure to use a monitor connector on
the graphics card.
Ethernet connector Used to attach an Ethernet cable for a local area network (LAN).
