A reception unit receives resource information transmitted through a network
and
constituted by a resource for version-up and an application program which applies
the resource and stores the resource information in an operation region of a storage
device. A decision unit decides whether an application occasion of the resource
stored has come or not. When it is decided that the application occasion has come,
an execution unit performs a process of copying the resource information in a maintenance
region of the storage device and making the maintenance region valid in the next
boot-up operation of a system.
