Description

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.

Used to send audio signals from the computer to external devices, such as powered stereo speakers (speakers with built-in amplifiers), multimedia keyboards, or the audio line-in connector on a stereo system or other external recording devices.

When used with 5.1 or 7.1 surround-sound speakers, this connector should be attached to the front left and right speakers.

When used with 5.1 or 7.1 surround-sound speakers, this connector should be attached to the rear left and right speakers.

When used with 7.1 surround-sound speakers, this connector should be attached to the side left and right speakers.

When used with 5.1 or 7.1 surround-sound speakers, this connector should be attached to the center speaker or subwoofer.

Use this connector to attach an external hard disk drive.

Used to attach an Ethernet cable for a local area network (LAN).

Notes:

1.To operate the computer within FCC Class B limits, use a Category 5 Ethernet cable.

2.If your computer has two Ethernet connectors, it is recommended that you connect your primary Ethernet cable to the Ethernet connector marked as number "1" for optimal performance.

Used to send and receive IEEE 1394 signals between the computer and a compliant device, such as a video camera or external storage drive. This connector is sometimes called FireWire because it transmits data rapidly.

Used to attach a microphone to your computer when you want to record sound or if you use speech-recognition software.
