USB Hear it!

USB definition - telecom
A serial bus with a data transfer rate of 12 Mbps for connecting a microcomputer to peripherals such as keyboards, mice, printers, and digital cameras through a single, general purpose port. USB is a considerable improvement over the RS-232 interface, but does not compare favorably with IEEE 1394, also known as FireWire in the Apple computer domain. See also 1394, bus, FireWire, IEEE, microcomputer, peripheral, port, RS-232, and serial.
