Chapter 2: About USB
USB, which is short for Universal Serial Bus, is a technology designed to
make connecting devices to computers easier. First developed in 1996 by a
group of computer industry leaders that included Compaq, Digital, IBM, Intel,
Microsoft, NEC, and Northern Telecom, USB is one of the most widely used
technologies for users who want to add peripherals to their computers.
USB is unique because it is Plug-and-Play, which allows a computer to instant-
ly recognize when a device like a keyboard, mouse, or scanner has been con-
nected to it. Once the device has been recognized, it’s ready to go—no special
setup is required. Similarly, USB supports hot-swapping, the insertion or
removal of devices while the computer is turned on. You can swap one device
for another without having to power down your system or install any special
software—it really is that easy.
The USB 1.1 standard supports two speed modes, 1.5 and up to 12Mbps. The
newest USB standard, USB 2.0, supports three speed modes: 1.5, 12, and up to
480Mbps. The new USB 2.0 devices are fully backward compatible with earli-
er USB devices. USB 2.0 offers you increased functionality and additional
bandwidth, allowing you to add more peripherals to your computers.
