问题     Digital technologies are fast becoming indispensable. A growing array of devices and technologies are on offer today, making users much more mobile.
    While it took around 21 years to reach the first billion mobile users, the second billion signed up in just three years.
    Therefore, it is not surprising that in today’s world, digital business becomes big business.
The clearest evidence for this is at the macro-economic level, where the contribution of ICTs to the general economy has grown rapidly, regardless of falling prices.
    Mobile, broadband, user-generated content and IPTV are some of the technologies highlighted as the underlying enablers of new lifestyles.
    The report, part of a series written yearly by ITU, explores the changing nature and role of the digital individual and of digital identity with examples and scenarios.

答案 数字技术正在迅速成为不可或缺的因素。2.如今可供选择的工具与技术不断增多,用户的移动性也随之提高。 移动用户在大约21年的时间里发展到十亿,而只用了3年就发展出了第二个十亿。 因此数字产业成为当今世界上的大型产业并不奇怪。 宏观经济为此提供了最有力的印证:尽管价格持续下降,信息通信技术对总体经济的贡献却迅速增长。 报告重点介绍了移动、宽带、用户自创内容和交互式网络电视等促成新型生活方式的根本技术。 作为国际电联年度系列报告的一部分,本报告通过实例和情境研究了数字个人和数字身份不断变化的实质和作用。 “数字生活”报告表明,人类生活与技术日益融合,于是,虚拟身份得以创建,数字人物因娱乐、商业甚至有时是不轨意图而存在。
