An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, 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. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.

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.

Parameters representing types of machines to be connected to a network, connection types thereof to the network, and operation modes thereof in the network system are set from an information processing apparatus. The obtained parameters are written as parameter files on a recording medium. In each network machine, a network system is automatically constructed by referencing the files. Consequently, the parameter setting operations for the installation of the machine are simplified and there is achieved automation of operations in each network machine.

An information processing system in which update processes are automated in conformity with types of client machines, to thereby dispense with manual version update processes, and within which redirectors of identical version are run at any time, to thereby prevent any error ascribable to different programs from occurring. When a redirector stored in the client machine is started, it notifies version information of its own to a configuration management program stored in a server machine. In a case where version information of a redirector stored in a configuration management database is newer than the notified version information, the configuration management program sends an update request back to the redirector of the client machine and transfers the new redirector to the client machine so as to update the redirector thereof.

Computer controlled method and system capable of preserving information

A facsimile server system which can be utilized similarly to a stand-alone FAX. A remote FAX includes a scanner, a printer and a FAX communication unit. A client delivers document data to a FAX server, and makes a request for FAX transmission/printing. The FAX server expands the document data requested to be transmitted, into image data, and it transfers the image data to the appropriate remote FAX and gives a command for the FAX transmission/printing. When instructed to perform FAX transmission directly by a user, the remote FAX accepts the image of a handwritten document, and it subsequently delivers the image data of the document to the FAX server and makes a request for the FAX transmission. Besides, when the remote FAX has been commanded to scan image data or has received image data as FAX reception, it delivers the scanned image data or the received image data to the FAX server. Then, the FAX server accumulates the image data and offers them to the client in accordance with a retrieval process.

A virtual machine for operating, on a base machine, applications software for a target machine. The virtual machine includes first display control hardware for the base machine, second display control hardware for the target machine, a virtual machine monitor for emulating the operation of the target machine by utilizing the second display control hardware for displaying operation, and a selector for selecting one of the first display control hardware and the second display control hardware depending on whether the virtual machine monitor is operable in a target machine mode or a base machine mode. The OS of the base machine is utilized for the virtual machine without modification.

When display data having a smaller vertical number of pixels than a vertical number of pixels of a display is to be displayed, a display status can be switched during the execution of any application software. When a display selection switch receives a switch command, it outputs a selection signal directly to a display controller, an address generator in the display controller selects one of display modes to the display in accordance with the selection signal. When the display data having the smaller vertical number of pixels than the vertical number of pixels of the display is to be displayed, a user can freely select the display mode without interruption of a CPU during the execution of any application software.

A gradation conversion system comprising: a plurality of gradation conversion devices for converting color display data into gradation display data by different gradation conversion methods, respectively; and switching device for selectively activating one of the plurality of graduation conversion device. Accordingly, if a number of different colors are to be displayed in the same number of gradations when converting multi-color display data into gradation display data, it is possible to perform this gradation conversion. On the other hand, if different colors are to be displayed in gradations as exact to the brightnesses of colors as possible, it is possible to select one of plural gradation conversion methods so as to carry out this gradation conversion.

Gradation conversion system for converting color display data into

A key input device including a plurality of keytops, with an elastic member being disposed between each keytop and a printed circuit board so as to be supported at a lower end portion thereof by an upper surface of the printed circuit board and pushed upwardly to cause the keytop to be biased upwardly. An engaging portion, provided on a main body of each keytop, prevents the keytop from coming out of a hole accommodating the respective keytops. The depressing stroke of the respective keytops can be defined by an upper casing an the printed circuit board regardless of the state of elastic deformation of the elastic member. An insulating substrate may be provided on the printed circuit board, with printed electrodes being formed on an upper surface of the insulating substrate in an opposed relationship to the keytops in such a manner that, when one of the keytops is depressed, the printed electrodes are brought into contact with the contact electrodes corresponding to the depressed keytop. Printed wiring conductors or strips can be formed on the upper surface of the printed circuit board on which the printed electrodes for the keytop switches are formed. The circuit elements or electronic components, connected through the printed wiring conductors or strips, can be mounted on the lower surface side of the printed circuit board resulting in a common printed circuit board for holding the keytop switches and the mounting of the electronic components.
