1.2 What is U&I?
U&I incorporates two of the most common and fastest interfaces on the market today, meeting the demands for speed,
flexibility and ease of use in a wide variety of applications. In "U&I," the "U" stands for USB and the "I" stands for
"IEEE 1394."
USB 2.0
The new USB 2.0 standard provides higher bandwidth for high-speed peripherals such as external hard drives, high-speed
scanners and tape drives. USB 2.0 delivers transfer rates up to 480Mb/s, while conveniently maintaining backward
compatibility with USB 1.1 devices.
USB 2.0 can still be used to connect lower-speed USB 1.1 ports and devices like digital cameras, scanners, modems,
keyboards, mice, joysticks and printers. In the USB 2.0 system, existing USB peripherals do not have to be upgraded, and
lower-speed devices will not require additional performance, instead operating as USB 1.1 devices.
USB Icons
These icons will help you easily identify the USB interfaces. They appear on USB cables and next to the USB port connectors
on certain computers.

FireWire/IEEE 1394
FireWire is Apple's implementation of IEEE 1394, and is capable of transferring large amounts of data between computers
and peripherals at a high rate of speed. The FireWire standard defines 100, 200 and 400Mb/s devices and can support
multiple speeds on a single bus.
With FireWire, there is no need for terminators, device IDs, screws, or complex setup, and the standard supports free-form
daisy chaining for peer-to-peer implementations. A fast, cross-platform serial bus, FireWire is ideal for use with multimedia
peripherals and high-speed devices such as digital video cameras and hard drives.
