技术进步为电信业腾飞奠定基础在信息技术迅猛发展并获得广泛应用的今天,我们很难想象,如果没有移动电话和微机,如果电传速度很慢、价格很高,以致多数人都不使用它,如果因特网上总共只有4台主机,WWW 网也不存在,因而没有电子邮件,如果没有微软公司,世界会是什么样子。1971年以后,电信技术方面出现了一系列重要进展。10年后,MS—DOS 软件被用在了第一台 IBM PC上;20年后,Tim Berners—Lee 在欧洲核子中心(CERN)建立了 WWW 网。计算机功能和速度的迅速提高以及各种形式的电话系统大幅席降价,导致了信息技术的广泛应用。此外,还出现了像蜂窝电话这样的新事物,这些新事物从根本上改变了我们的生活方式。30年之前没有人能预言1997年末世界上会有两亿多人有自己的手机;也无法设想会有一亿多人能够通过
Technological advances to lay the foundation for the take-off of the telecom industry Today, with the rapid development and widespread use of information technology, it is hard to imagine that without telecoms and microcomputers, if telefax is slow and expensive, most people will not use it If there is only a total of 4 hosts on the Internet, WWW does not exist, so there is no e-mail, if not Microsoft, the world will look like. After 1971, a series of important developments have taken place in the area of telecommunications technology. Ten years later, MS-DOS software was used on the first IBM PC; 20 years later, Tim Berners-Lee set up a WWW network at CERN. The rapid rise of computer functions and speed, and the drastic price reduction of various forms of telephone systems have led to the widespread application of information technology. In addition, there are new things like cell phones that have fundamentally changed our way of life. No one can predict 30 years ago that over 200 million people in the world will have their own mobile phones by the end of 1997; nor can we imagine that over 100 million people will be able to pass
