A system is provided for preventing recorded data from being illicitly read out and analyzed. An Internet connection interface transmits a program executed by an adapter to an authentication station, while receiving the program in an encrypted form from the authentication station. A hard disc records the encrypted program, received from the authentication station. An interface transmits the program recorded on the horizontal direction on the adapter.

Information processing system

A program supplied from a personal computer via an interfaceis processed according to a program stored in a ROM, developed in a RAM, and executed by a CPU. Data resulted from the program execution is stored into a nonvolatile memory. The interface, CPU, RAM, nonvolatile memoryand ROMare housed in an adaptorformed integrally as a semiconductor IC.

A frequency control apparatus and an information processing apparatus includes an observation section for observing an operation state of a control object which operates with a variably controlled frequency, a frequency determination section for determining a clock frequency in response to the operation state, and a frequency limitation section for limiting a range or a value of the clock frequency determined by the frequency determination section. If the frequency determined in response to the operation state of the control object is within an allowable range, the control is performed with the frequency, but if the frequency is outside the allowable range, the frequency is limited to the range.

A cable apparatus makes a selection between supply of an internal power to a predetermined interface device and that of an external power to the interface device in compliance with the interface standard applied to the predetermined interface device. The cable apparatus includes an internal power terminal connectable to an internal power source, a plurality of external power terminals connectable to an external power source, and a plurality of power lines connected to the internal power terminal and/or external power terminals. A power line selection controller is included to select, when an internal power is supplied from the internal power terminal, one of the power lines that allows a connection of the internal power from the internal power terminal to the plurality of external power terminals and when an external power is supplied from any one of the external power terminals, one of the power lines that allows to connect the external power from the external power terminal to the other external power terminals.
