High Quality Content by WIKIPEDIA articles! A USB hub is a device that expands a single USB port into several so that there are more ports available to connect devices to a host system. USB hubs are often built into equipment such as computers, keyboards, monitors, or printers. When such a device has many USB ports they all usually stem from one or two internal USB hubs rather than each port having independent USB circuitry. Physically separate USB hubs come in a wide variety of form factors: from external boxes (looking similar to a network hub) connectible with a long cable, to small designs that can be directly plugged into a USB port. In the middle case, there are "short cable" hubs which typically use an integral 6 inch cable to slightly distance a small hub away from physical port congestion and of course increase the number of available ports.
