Some notebooks and even some PDAs use Port Replication or Docking Stations. These docking stations sit at the desktop, waiting for the return of the notebook. This makes it simpler to hook up an external monitor, printer, mouse, etc. once at 'home port'.
The docking station is usually a long rectangular device with all the ports necessary to add a full size keyboard, monitor, or mouse. The notebook or laptop computer simply plugs (docks) into the station, and then un-plugs and goes with you when you travel.
This is very convenient for the person who wishes to use one computer and leave all the peripherals behind.
As laptops or notebooks have become full featured and powerful in terms of CPU speed, RAM and hard drive size this is a practical option for many.
