Abstract: According to one embodiment, an information processing apparatus manages client terminals belonging to groups organized hierarchically. The information processing apparatus includes an image file generator, a permitted group setting module and a delivery controller. The image file generator generates a disk image file for a first group of the groups, the disk image file including a first OS and a first application program. The permitted group setting module sets a second group of the groups to be a permitted group to which delivery of the disk image file is permitted, wherein the second group is subordinate to the first group. The delivery controller delivers the disk image file to a client terminal belonging to the first group and a client terminal belonging to the permitted group.

Abstract: According to one embodiment, an electronic apparatus, which is driven by power supplied from a battery, includes a delivery information receiver, a first residual capacity estimation module and a file receiver. The delivery information receiver receives delivery information indicative of a file and a priority of the file, the file being to be delivered from a server. The first residual capacity estimation module estimates a first residual capacity of the battery at a time of completion of download of the file. The file receiver receives the file from the server if the first residual capacity is equal to or greater than a threshold based on the priority.
