<p>PURPOSE:To reduce a line use charge by transmitting data to a terminal equipment, for which a distance to a central information processing part is short, executing the data transmission from the terminal equipment to the other terminal equipment which is shortly distant, successively repeating the operation between the terminal equipments and executing the data transmission. CONSTITUTION:The data such as a program, etc., are transmitted from a host computer C as the central information processing part to a terminal equipment POS0 and the terminal equipment POS0 to receive the transmission of the data transmits these data to a next terminal equipment POS1. After that, the data transmission is successively repeated to POS1, POS2, POS3 and POS4. In such a case, for the line use charge when the data transmission is wholly finished from the computer 5 to all the five terminal equipments, since a frequency in each line is 1, the total sum of the frequency goes to be 5. Accordingly, in comparison with a case that the transmission is separately executed from the computer C to the POS0-POS4, the line use charge is lowered.</p> |
