Abstract
An information processing apparatus having a resume function which can maintain security even when a plurality of users use a common information processing apparatus. A work state at a power-off time is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for the resume operation function on a main memory for each user. When a power source is turned on again, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. A work state preservation file on a file server apparatus in a network has a resume function which does not need battery back-up. When this information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each of users, thereby realizing a resume function that is excellent in terms of security and utility.
