USB
Ports
The USB ports provide a hardware interface for low-speed peripher-
als 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 12 Mbits/sec
(equivalent to 1.5 Mbytes/sec), and up to 127 devices can be at-
tached. Fast devices can use the full bandwidth, while lower-speed
ones can t ransfer data using a 1.5 Mbits/sec sub-channel.
