ABSTRACT:
If an information item tried to be accessed during traveling is stored in a memory unit, an identifier indicating the information item is registered in an unaccessed-information management unit. If, on the other hand, the information item is stored in the memory unit, the information item is displayed and the identifier is registered in an old information access management unit. When a portable information processing apparatus has come to be able to be connected to a network, an information item indicated by the identifier registered in the unaccessed-information management unit is taken in from a server. Further, whether or not the information item indicated by the identifier registered in the old information access management unit is of an updated version is determined on the basis of the storage date of the information item and the creation date of the information item stored in the server and indicated by the identifier. If the information item is not of the updated version, the information item stored in the server is taken in. As a result, the updated version of an information item tried to be accessed when the information processing apparatus could not be connected to the network can be effectively taken in when the processing apparatus has been connected to the network.
