Docking station 扩展坞
In computing, a docking station or port replicator or dock provides a simplified way of "plugging-in" an electronic device such as a laptop computer to common peripherals. Because a wide range of dockable devices—from mobile telephones to wireless mice—have different connectors, power signaling, and uses, docks are not standardized and are therefore often designed with a specific make and model of a device in mind.
