Abstract :
Universal serial bus technology has made it easier to connect peripherals to PCs than prior methods, such as serial and parallel ports. USB lets users attach peripherals and other devices - such as digital cameras, game controllers, hard drives, printers, and scanners - without having to install individual drivers or use expansion cards, all without rebooting the computer. However, USB requires connections via cables, which can become a jumble when many devices are involved. And the cables limit the distance over which users can connect devices. To address this issue, a number or companies, are beginning to release products based on wireless USB.
