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.
