Data processing device, data management method, storage medium of storing computer-readable program, and program
摘要:
A data processing device comprises a second storage unit for storing data accessed in a first storage unit, and compares data read from the first storage unit with the data stored in the second storage unit. Thus, the data processing device judges whether or not the first storage unit is a predetermined device.
