A plurality of terminals connected to a network distribution-process update notifications of information and data obtainment, thereby constructing an information notifying network which needs no server. In the network constructed by a plurality of terminals, when the user updates the information on the terminal, each terminal functions as an information provider terminal for informing another terminal that the information has been updated and transferring the updated information, and when another user updates the information on another terminal, each terminal functions as an information receiver terminal for receiving the update notification from the information provider terminal and the updated information.
