<p>PURPOSE:To make a client to retrieve the file of a server anytime in a free time by managing the power source disconnection by the client, by the server. CONSTITUTION:When a power switch 101 is depressed, it is detected by a power source disconnection information transmitting and receiving part 103, and the information is transferred through line control parts 105 and 107 to a power source disconnection managing part 108. The power source disconnection managing part 108 deletes the pertinent client information from a client connection information table, and returns a disconnection response. A client 100 disconnects its own power source at the time of receiving the disconnection response from a server 106. The server side disconnects its own power source after receiving the power source disconnection information from the entire clients. Thus, the client can retrieve the file of the server anytime in the free time.</p> |
