One of the great ease-of-use technologies is the Universal Serial Bus specification, developed by a nonprofit industry group, the USB Implementer's Forum. The forum created USB 1.0 and the upgrade, USB 1.1. Things got even better with the introduction of USB 2.0, a much faster, backward-compatible specification. Simple enough, right? Well, soon enough the marketers at the USB Implementer's Forum got hold of the branding. Now we have several new names for old things. USB 1.1, at a signaling rate of 1.5 Mbps, is now known as Lo-Speed USB. USB 1.1, at 12 Mbps, is called Full-Speed USB. And USB 2.0, at 480 Mbps, is Hi-Speed USB.

For more ease and greater confusion, the group has also introduced USB On-The-Go and Hi-Speed USB On-The-Go. With these supplements, you can connect devices--say, a digital camera and a PC--without a host between them.
