Explaination
- Universal Serial Bus. USB is a standard port that enables you to connect external devices (such as digital cameras, scanners, and mice) to Windows 98 and Macintosh computers. The USB standard supports data transfer rates of 12Mbps (USB1.0) and 400Mbps (USB2.0) . Aside from speed advantages, USB devices can be connected or disconnected without the need to restart the computer (hot swap/plugging). Many USB devices can work on either a Windows 98 PC or a Mac, provided the device manufacturer offers connectivity software for both computer systems. Many of the latest digital cameras offer USB as well as serial connections.
A single USB port can be used to connect up to 127 peripheral devices (daisey chain).
A common form of data storage now is the external USB stick. These are available in capacities from 32MB up to 512MB, However there are external Mobile HDD USB2 in capacities upto 80GB. (see www.Freecom.com)
