ABSTRACT:
A data transmission method is provided for a multi-computer system which has a plurality of computers mutually connected via a transmission line. The plurality of computers are divided into groups, with an address assigned to each group. Transmission data of a sending computer is provided with a location where the address is assigned and a location where a content code indicating the data content is assigned. The sending computer transmits the data with either the address or content code assigned, and the computers other than the sending computer decide whether or not to receive the data according to either the address or the content code.
