PURPOSE:To curtail an overhead of a CPU side by writing directly a large quantity data such as image information to a magnetic disk device by a communication control processor. CONSTITUTION:A network control program 15 of a communication control processor 10 analyzes an information header, and in case of load information, the information concerned is set to a transfer buffer to a CPU, but in case of image information, furthermore, an image information header and image information ID are set to the transfer buffer to the CPU. In this case, the image information is not outputted to a magnetic disk device, and a managing place on a disk and managing information are set beforehand from magnetic disk managing information of the program 15. As for write to the magnetic disk device of the image information, and a transfer for the transfer buffer to the CPU, a separate task or a separate processor executes them by keeping pace with an information input processing. In this way, the quantity of a transfer data to the CPU 20 is curtailed, and an overhead is curtailed.
