Abstract
The network computer (“NC”) stores a replica list in a local storage by an initial downloading of a synchronization list in a server computer as well as resource replicas that are necessary for mobile operation of the NC. When the NC returns to an on-line state to the server, the replication between the resource replicas in the NC and the server resources is performed with reference to the synchronization list and the replica list in the local storage. Even if a synchronous object in the server synchronization list has been modified during the mobile operation of the network computer, the NC can determine the modification in the replication process. This results in a reliable and flexible network computer system.
