The Fifth Generation of Computing
(after Mainframe, Personal Computer,Client-Server Computing, and the web)
尼古拉斯·卡尔(Nicholas G. Carr)的新书《IT不再重要:互联网大转换的制高点--云计算》,这本书的原名是 《巨大的转变: 从爱迪生到谷歌,为世界重新布线》(The Big Switch: Rewiring the World, from Edison to Google),书中提出了IT将向公用计算模式转变的趋势。这本书可以说是2003年5月尼古拉斯.卡尔在《哈佛商业评论》(Harvard Business Review)发表的题为《IT Doesn’t Matter》的文章的详细阐释。在那篇文章里,他掀起了一场轩然大波,一场质疑IT价值、触及整个IT业命运的世纪论战由此开火。
作为《哈佛商业评论》前编辑的尼古拉斯·卡尔,因其《IT不再重要》(IT Doesn’t Matter)一文而名噪天下。在这本书中,尼古拉斯.卡尔认为,我们现在正处于计算性质出现根本转变的早期阶段,即从个人和公司需要通过自己的机器和自己安装软件在本地提供计算,变成这样的公用模式: 许多计算功能由大型中央站即大型中央公用计算公司通过网络来提供。这就好比100年前机械动力出现的一幕,当时电力公用事业公司改变了这种资源的性质以及公司和个人使用及获取电力的方式。

不远的将来,随着“云计算”的发展,廉价和方便将会使越来越多的学校和个人把自己的信息处理迁移到“云”上。这将促使人们在考虑教育信息化的发展策略时要有前瞻性眼光,眼前的硬件和软件建设“够用就好”,要提前着手探索“云计算”时代对教育资源建设、教学方式变化的影响,研究教育信息化的“云”机制,研究学校的网络中心、教育技术机构的重新定位。同时,将引发教育技术观念的更新:
一切皆服务(everything as a service)、事事可在线(everything online)、更快更方便(everything easy and quick)、更加个性化(everything personal)。
From Literacy to …
