电子计算机技术与通讯技术日益密切结合是最近时期中科学技术发展的一个重要趋势,远距离快速传输数字信息的通信技术与快速处理数据的电子计算机技术相结合,实现了远程计算,创立了计算机网络。它的出现扩大了计算机的应用范围,显著地提高了计算机的应用水平,对科学技术,工业生产,交通运输,财政贸易,国防军事,文化教育以及社会活动的各个方面都带来了深刻的影响。也正是计算机的日益广泛地应用,在激励着数据通信技术的发展。快速的信息处理和快速的数据传输的有机结合,导致“信息化”社会的到来。
The increasingly close combination of electronic computer technology and communication technology is an important trend in the development of science and technology in the recent period. The combination of communication technology for fast transmission of digital information over long distances and electronic computer technology for rapid processing of data enables remote computing and creation of a computer network . Its emergence has expanded the range of applications of computers, significantly increased the level of application of computers and profoundly influenced all aspects of science and technology, industrial production, transportation, finance and trade, defense and military affairs, cultural education and social activities . It is also the increasingly widespread use of computers, encouraging the development of data communications technology. The combination of rapid information processing and fast data transmission leads to the arrival of an “informationalized” society.
