A server delivers new software to each of clients through the network. After delivering new software, the server sends a notification of switchover from old software to new software to each of the clients through the network. Each client loads the new software having been received on a memory. Receiving the notification from the server, each client switches the old software to the new software. The switchover operation at client is carried out in short time by rewriting address on memory without suspension of a service. In case of canceling the update, the reversion operation from new software to old software is carried out in an analogous way to the switchover operation.
