临近世纪之交,一场由美国率先掀起的信息高速公路浪潮,迅速波及全世界。借用“高速公路”这个人人皆知的词语来形象地表达这种新技术,通俗地讲就是在比头发丝还细的透明光纤形成的“高速公路”上往返穿梭着看不见、摸不着的经过处理的多方信息。从专业术语上说,信息高速公路即是光纤宽带综合业务网,用光缆将通信网、计算机网和有线电视网等联接、延伸、扩展,使之遍布全国,同时可通过数字压膜技术.大大提高光缆传输能力。换言之,即采用先进的计算机加密、解密、多媒体等技术,通过电话、电脑、电视传真等多 As we approach the turn of the century, a wave of information superhighways led by the United States has rapidly spread to the entire world. Use the well-known words of “highway” to express vividly this new technology, which is more commonly known as “highway” made of transparent fiber thinner than hair wire, which can not be seen and touched Processed multi-party information. In terms of technical terms, the information superhighway is an optical fiber broadband integrated service network, which uses optical fiber cables to connect, extend and extend communication networks, computer networks and cable television networks to enable them to spread all over the country and at the same time, through digital lamination technology. Improve cable transmission capacity. In other words, using advanced computer encryption, decryption, multimedia and other technologies, by telephone, computer, television and fax and more
