PROBLEM TO BE SOLVED: To provide a high-speed and efficient data transmitting/receiving method capable of reducing the load of a CPU at the time of transmitting/ receiving large capacity data such as moving images by a computer terminal or the like. SOLUTION: The network interface device is provided with at least one I/O port Pn differently from a bus for inputting/outputting data to/from a host CPU as the 1st feature. The system is also characterized by loading a storage means for storing a table previously defining prescribed identifiers corresponding to respective I/O ports Pn and a local CPU for selecting a means P for outputting an identifier described in the header of a received packet from the table so as to select one or more output destinations from the bus or the I/O ports Pn in each packet and distribute received data to the output destinations.
