Universal Serial Bus Ports
You can connect two USB devices or USB hubs to the USB ports.
The USB ports provide a hardware interface for low-speed
peripherals such as the keyboard, mouse, joystick, scanner, printer
and telephony devices, and also support MPEG-1 and MPEG-2
digital video. The USB ports have a maximum bandwidth of 480
Mbits/sec (equivalent to 60 Mbytes/sec), and up to 127devices can
be attached. Fast devices can use the full bandwidth, while
lower-speed ones can transfer data using a 60 Mbytes/sec
sub-channel.
Audio Line-In Port
You can connect a tape player or another audio source to the light
blue Line-in connector to record audio on your computer or to play
audio through your computer’s sound chip and speakers.
