Universal Serial Bus

In information technology, Universal Serial Bus (USB) is a serial bus standard to interface devices to a host computer. USB was intended to allow many peripherals to be connected using a single consistent interface socket and to get better the plug-and-play capabilities by allowing hot exchange, that is, by allowing devices to be connected and disconnected without rebooting the computer or rotating off the device. Other suitable features comprise providing power to low-consumption devices without the require for an external power provide and allowing many devices to be used without requiring manufacturer exact, individual device drivers to be installed.

USB is intended to replace many legacy varieties of serial and similar ports. USB can connect computer peripherals such as mouse, keyboards, PDAs, gamepads and joysticks, scanners, digital cameras, printers, personal media players, and flash drives. For many of those devices USB has become the standard connection method.
