Connector Description
USB connectors Used to attach a device that requires a Universal Serial Bus
(USB) connection, such as a USB keyboard, USB mouse, USB
scanner or USB printer. If you have more than six USB devices,
you can purchase a USB hub, which you can use to connect
additional USB devices.
Ethernet connector Used to attach an Ethernet cable for a local area network
(LAN).
Note: To operate the computer within FCC Class B limits, use
a Category 5 Ethernet cable.
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.
Microphone connector Used to attach a microphone to your computer when you want
to record voice or other sounds on the hard disk if you use
speech-recognition software.
