U niversal S erial B us ( USB ) is a serial bus standard to interface devices. USB was
designed to allow peripherals to be connected using a single standardized
interface socket and to improve Plug-and-play capabilities by allowing devices to
be connected and disconnected without rebooting the computer (hot-swapping).
Other convenient features include providing power to low-consumption devices
without the need for an external power supply and allowing many devices to be
used without requiring manufacturer specific, individual device drivers to be installed.
USB can connect computer peripherals such as external hard drives storage
devices, keyboards, PDAs, scanners, digital cameras, printers, personal media
players and flash drives. For many of those devices USB has become the
standard connection method.

USB 3.0: A Supper-Speed (USB 3.0) rate of up to 5,000 Mbits/s (1GB/3.3sec)
