USB
USB (Universal Serial Bus) is a data communications standard that allows your computer to recognize
(auto-detect) new devices. No technical expertise is required to install your device. You simply plug your
USB cable in and follow a limited set of easy-to-understand, automatically generated instructions. Set-up
and operation has never been easier.
Advantages of USB
1. There is no need for numerous different types of ports and connectors on your computer. Modems,
printers, joysticks, keyboards, mice, audio devices, CD-ROMs, digital cameras and other devices can
all be connected through USB.
2. With USB, installing adapter cards, changing dip switches and configuring IRQs (Interrupt Requests)
does not require opening your computer.
3. USB has data transfer rates of up to 12 Mbps.
4. Multiple devices can be daisy-chained to a single port without restarting your computer.
5. USB can power some devices - eliminating the need for batteries or power adapters.
