一、Internet的发展超过了历史上任何一种通信方式 自从1995年以来,Internet的用户数得到了指数增长,1995年底,全世界的Internet的用户数1600万户,到1998年底达到1.6亿户,增加了10倍;1999年底可望达到4亿户。接入Internet的主机数也得到了快速增长,1995年底在Internet上工作的主机数大约1400万台,到1998年底增加到4350万台,增加了3倍。ITU统计过电话机、无线电、计算机、电视机和Internet主机数到达5000万台所经历的时间。电话机用了74年,无线电38年,计算机16年,电视机13年,而Internet的主机数仅花4年时间。
First, the development of the Internet has exceeded any of the previous types of communications Since 1995, the number of Internet users has grown exponentially. By the end of 1995, the number of Internet users worldwide reached 16 million, reaching 160 million by the end of 1998, An increase of 10 times; the end of 1999 is expected to reach 400 million. The number of hosts accessing the Internet has also increased rapidly. By the end of 1995, the number of hosts working on the Internet was about 14 million, increasing to 43.5 million by the end of 1998, a threefold increase. The ITU statistics show that the number of telephone, radio, computer, television and Internet hosts has reached 50 million. The phone took 74 years, 38 years for radio, 16 years for computers and 13 years for TVs, while the number of Internet hosts only took four years.
