In this time, we experimented to compare the sending time of some data with none MNP and MNP over class 4. At the last experiment, we have been sent some compressed data in order that had more quickly to send a communication speed of modem than communication efficiency, but it has a fault for time loss. Because a sender need to compress a send data and an addressee extend to need a receive data. So, we maked an experiment with MNP class 4, 5 and 7 data modem that used a sort of data according to a characteristic of data, an image data and so on. Then we could confirmed to send the character and the image data over the maximum communication speed of 4800bps on the voice line of INMARSAT.","subitem_description_type":"Abstract"},{"subitem_description":"今回の実験においておよそ次のことがいえる。 (1)英文平文を伝送する場合MNP Class 7のみを用いて伝送すれば,高速かつ正確なデータ伝送が可能である。 (2)日本文平文では,MNP Class 7のみ,またはおなじくZMODEMを併用した場合通信効率200%で最も効率の高いデータ伝送が可能である。 (3)実行型COM, EXEファイルでは,MNP Class 5, 7とYMODEM-gおよびZMODEM併用の場合の通信効率が143%～149%で効率の良いデータ伝送が出来る。 (4)画像ファイルでは,MNP Class 5とZMODEMを併用した方が,高速かつ正確な画像のデータ伝送が可能である。 (5)圧縮ファイルを使用してMNP Class 4とYMODEM-gまたはZMODEMを併用すれば,英文平文,日本文平文,MS-DOS実行型EXE, COMファイルおよび画像ファイルをさらに高い通信効率でデータを伝送する事が出来る。上記の事より,MNP MODEMでは通信効率は,必ずしもクラスの上位のプロトコルが,最良とはいえない。伝送するデータの種類により,適宜上記の結果を参考として,ケースバイケースで使用すれば,経済的かつ通信の三要素を満たすデータ伝送が可能である。","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.70, pp.29-43;
