Universal Serial Bus Tree Structure
USB (Universal Serial Bus) is a specification to establish communication among components and a host controller (typically personal computers). USB is intended to replace several varieties of parallel and serial ports. USB can attach computer peripherals likewise, keyboards, digital cameras, mice, printers, flash drives, external hard drives, and personal media players. For several of those devices, USB has become the usual connection method. USB was designed for PC[citation needed], but it has become commonplace on other components such as PDAs ,smart phones and video game consoles, and as a power cord among a device and an AC adapter plugged into a wall plug for charging. As of the year 2008, there are approximate 2 billion USB devices sold per year, and about 6 billion totals sold to date.
