DATA COMMUNICATION SYSTEM

摘要

PURPOSE:To efficiently transmit data by the data communication system which sends transmitted data to an opposite destination through a line. CONSTITUTION:This data communication system is equipped with a compressing means 11 which compresses the transmitted data when a request to send the transmitted data is made or when the non-issue of the request to send the transmitted data is guaranteed and a comparing means 13 which compares the data size of the data compressed by the compressing means 1 with the data size of the transmitted data. Further, this system is equipped with a transmitting means 14 which sends the transmitted data as they are to the opposite destination when the comparing means 13 judges that data size of the compressed transmitted data is small or sends the data compressed by the compressing means 11 to the opposite destination when the comparing means judges that the size is small.
