New Processors Open New Era of IT Technologies
Last week, Intel introduced to the public in Russia and other CIS countries a family of processors Intel Xeon E5-2600. They are more powerful and reliable and, importantly, are very economical in terms of energy consumption. Their presence opens a new era in the field of IT technologies and means that the cloud technology is getting closer.
These processors are primarily designed for servers, data centers (DPC) and supercomputers. The emergence of this class of devices is not accidental. According to the regional director of Intel in Russia and other CIS states Dmitri Konash who spoke at the event, the market of IT-technology is developing so rapidly that, according to forecasts, by 2015 there will be 15 billion devices connected to the Internet, and over 3 billion of active users.
上周，英特尔公司向俄罗斯和其它独联体国家的公众推出了英特尔Xeon E5-2600系列处理器，它们更加强大可靠，尤其是在能量消耗方面更加经济实惠。它们的问世意味着IT技术领域开始了一个新时代，标志着云技术距离我们越来越近。
这些处理器主要是为服务器、数字处理中心和超级计算机设计的。这种处理器的出现并非偶然。根据英特尔公司俄罗斯和其他独联体地区负责人Dmitri Konash就此事发表的看法，IT技术市场的发展速度极快，根据预测，到2015年与英特网连接的设施将有150亿，用户超过30亿。

Tablet Computer
A tablet computer, or simply tablet, is a one-piece, mobile version of a personal computer, primarily operated by touchscreen (the user's finger essentially functions as the mouse and cursor, removing the need for the physical [i.e., mouse & keyboard] hardware components necessary for a desktop or laptop computer; and, an onscreen, hideable virtual keyboard is integrated into the display). Available in a variety of sizes,
even the smallest's touchscreens are much larger than those of a smart phone or personal digital assistant. A tablet computer may be connected to a keyboard with a wireless link or a USB port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include dual-touchscreens, and can be used as a notebook by displaying a virtual keyboard in one of them. Notes:
cursor [?k?:s?] n. 光标 swivel [?swiv?l] n. 旋轴；旋转接头
detachable [di?t?t??bl] adj. 可拆开的 stand-alone adj. 独立运行的
hybrids= hybrid computer混合计算机 booklet [?buklit] n. 笔记本式平板电脑
平板电脑，也叫平板，是个人计算机的一款，可移动，是一个整体。平板电脑主要依靠触屏操作（用户的手指发挥了鼠标和光标的作用，替代了台式和膝上电脑必须的物理硬件[即鼠标和键盘]。还有一个与显示器整合的可隐藏的屏幕虚拟键盘）。平板电脑型号多种，即使是最小的触屏也比智能手机或个人数字助理的屏幕大多了。可以用无线连接或USB插口给平板电脑连接一个键盘。可旋转笔记本电脑可以通过一个旋转铰链或一个滑动铰链把集成的键盘隐藏起来，仅仅在需要触摸时显示。混合型计算机配有一个可拆分的键盘，这样触屏可以当作一个单独
的平板电脑使用。笔记本平板电脑包括两个触屏，在其中一个触屏上显示虚拟键盘就可以作为笔记本使用。
