A data communication function table (15,25) relating to communication functions is shared between devices (1,2). Whether a communication device (1,2) can operate in an autonomous communication mode or request/response communication mode can be therefore determined, the data type can be determined, the data size and data identification information can be acquired, and a file can be divided to an optimum size for transmission. Network traffic is therefore reduced and the effective communication speed is improved for data communication between devices over a network. <IMAGE> |
