An arbiter system comprises a plurality of hardware resources, a common resource, and an arbiter. The plurality of hardware resources are divided into groups of hardware resources and are coupled to the common resource and the arbiter. The arbiter controls which of the plurality of hardware resources has priority to access to the common resource. The arbiter includes a group shifting arbiter which shifts priority among the groups of hardware resources and a level shifting arbiter which separately shifts priority among the hardware resources within each of the groups. An error checking value generator system comprises a general purpose DMA controller and an arithmetic circuit. The arithmetic circuit is coupled to receive data from the general purpose DMA controller. The arithmetic circuit generates an error checking value based on the data received from the general purpose DMA controller and based on a polynomial equation. The arithmetic circuit is capable of being programmed with a plurality of different polynomial equations usable to generate error checking values of different types.

The transfer of data between the adapter DMA controller and the adapter does not use any system CPU resources such as the data and address busses. The system CPU is free to use the system resources to continue operation. ing an operating state of said upgrading device. 6. A method of upgrading for a system, said system comprising a semiconductor memory and a cover, which is openable/closable, provided to an attachment part for holding a memory medium that stores information to be copied into said semiconductor memory, said method comprising the steps of: (a) detecting whether said cover is in open position or in closed position; and (b) executing copying process of said information in said memory medium into said semiconductor memory on the basis of a detection result obtained at said step (a). ng the step of compressing the encrypted data packet prior to transferring the encrypted data packet to the archive server. 4. The method of claim 3, wherein the encryption applet includes a compression program to compress the electronic data to form a compressed encrypted data packet. 5. The method of claim 1, wherein the encryption applet compiled by the software application is based on an encryption algorithm, and the encryption algorithm is changeable with respect to the software application. 6. The method of claim 1, further comprising the steps of: providing a plurality of encryption algorithms; selecting an encryption algorithm; and compiling the encryption applet using the selected encryption algorithm. 7. The method according to claim 1 wherein the first applet is further operable to perform the step of providing a secondary security key. 8. The method according to claim 7, wherein said secondary security key is a digital file lock. 9. The method according to claim 1 wherein a recipient is notified of an encrypted data file residing on the qualified server by an e-mail message sent via the open SSL protocol upon submittal of said data packet to said server. 10. The method according to claim 1 wherein said account qualifier is compared against a stored database. another computer; comparing said received positional information with positional information indicative of a place where the own computer is set; transmitting a response in such a case that said received positional information is coincident with the positional information indicative of the place where the own computer is set; and receiving said response by the computer which has firstly transmitted the positional information; and said first computer reading out necessary data from said another computer; and said first computer whose setting place is changed changing its setting condition based upon the read data to execute the process operation. 4. A cooperating method as claimed in claim 3, further comprising: a step for managing positional information related to a place where a computer is presently set and positional information related to a place where said computer was set in the past, and for comparing the past positional information with the present positional information, whereby a judgment is made as to whether or not the setting place of said computer is changed.
