A docking station (DockingStation) is a base used to expand the functions of a notebook computer. Through interfaces and slots, it can connect a variety of external devices, such as drives, large-screen displays, keyboards, printers, scanners, etc. It can make up for the defect that the thin and light notebook computer itself carries fewer accessories. This design allows users to enjoy the convenience and comfort of desktop computers in the office, and can give full play to the portability of notebook computers when working on the move.
