USB集线器

一个USB集线器

USB集线器英语:USB hub)是一个让多个USB设备连接到计算机上一个USB接口或另一个USB集线器上某个接口的设备。

USB集线器有时被集成到其它设备,例如键盘、显示器、打印机或者计算机机箱的前端。实际上,当一台计算机主机有多个USB接口的时候,它们都来自于主板内部一个或者两个主USB接口,而不是相互独立的硬件。理论上,一个主USB接口可以最多连接127个外围设备。

Hub Demo Board from VIA shows all internal components of a hub

A USB hub is a device that expands a single Universal Serial Bus (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.
