Abstract
It is made possible to maintain the security of one electronic device to which a plurality of other electronic devices are capable of being connected. To accomplish this, a notebook-type personal computer has an internal ROM storing ID information specific to this personal computer. The notebook-type personal computer is folded up and inserted into a docking station through an insertion port so as to be electrically connected to the docking station and rendered capable of executing processing that utilizes the resources of the docking station. The docking station has an internal non-volatile memory storing the IDs of notebook-type personal computers that are allowed to use the docking station. When a notebook-type personal computer is inserted into and connected with the docking station, use of the docking station is not allowed if the ID of this notebook-type personal computer has not been stored in the docking station.
