The Free On-line Dictionary of Computing (30 December 2018):
docking station
    A desktop mains powered unit into which a
   laptop or other portable computer can be connected via fixed
   connectors at the rear of the computer to provide quick and
   convenient connection of peripherals not normally used with
   a laptop.  These can include power supply, expansion cards,
   additional storage, an external monitor, network card,
   CD-ROM, full-size keyboard, printer, and mouse.  The
   alternative would require each of the above to be connected to
   the laptop individually.
