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。 [Ex 6] 1.

第一单元：计算机与计算机科学 课文A：计算机概览 一、引言 计算机是一种电子设备，它能接收一套指令或一个程序，然后通过对数字数据进行运算 或对其他形式的信息进行处理来执行该程序。 要不是由于计算机的发展，现代的高科技世界是不可能产生的。不同类型和大小的计算 机在整个社会被用于存储和处理各种数据，从保密政府文件、银行交易到私人家庭账目。计 算机通过自动化技术开辟了制造业的新纪元，而且它们也增强了现代通信系统的性能。在几 乎每一个研究和应用技术领域，从构建宇宙模型到产生明天的气象报告，计算机都是必要的 工具，并且它们的应用本身就开辟了人们推测的新领域。数据库服务和计算机网络使各种各 样的信息源可供使用。同样的先进技术也使侵犯个人隐私和商业秘密成为可能。计算机犯罪 已经成为作为现代技术代价组成部分的许多风险之一。 二、历史 第一台加法机是法国科学家、数学家和哲学家布莱斯.帕斯卡于1642年设计的，它是数 字计算机的先驱。这个装置使用了一系列带有10个齿的轮子，每个齿代表从0到9的一个数字。轮子互相连接，从而通过按照正确的齿数向前转动轮子，就可以将数字彼此相加。17世纪70 年代，德国哲学家和数学家戈特弗里德.威廉.莱布尼兹对这台机器进行了改良，设计了一台 也能做乘法的机器。 法国发明家约瑟夫―玛丽.雅卡尔，在设计自动织机时，使用了穿孔的薄木板来控制复 杂图案的编织。在19世纪80年代期间，美国统计学家赫尔曼.何勒里斯，想出了使用类似雅 卡尔的木板那样的穿孔卡片来处理数据的主意。通过使用一种将穿孔卡片从电触点上移过的 系统，他得以为1890年的美国人口普查汇编统计信息。 1、分析机 也是在19世纪，英国数学家和发明家查尔斯.巴比奇，提出了现代数字计算机的原理。 他构想出旨在处理复杂数学题的若干机器，如差分机。许多历史学家认为，巴比奇及其合伙 人，数学家奥古斯塔.埃达.拜伦，是现代数字计算机的真正先驱。巴比奇的设计之一，分析 机，具有现代计算机的许多特征。它有一个以一叠穿孔卡片的形式存在的输入流、一个保存 数据的“仓库”、一个进行算术运算的“工厂”和一个产生永久性纪录的打印机。巴比奇未 能将这个想法付诸实践，尽管在那个时代它在技术上很可能是可行的。 2、早期的计算机 模拟计算机是19世纪末开始制造的。早期型号是靠转动的轴和齿轮来进行计算的。用任 何其他方法都难以计算的方程近似数值，可以用这样的机器来求得。开尔文勋爵制造了一台 机械潮汐预报器，这实际上就是一台专用模拟计算机。第一次和第二次世界大战期间，机械 模拟计算系统，以及后来的电动模拟计算系统，在潜艇上被用作鱼雷航线预测器，在飞机上 被用作轰炸瞄准具的控制器。有人还设计了另一个系统，用于预测密西西比河流域春天的洪 水。 3、电子计算机 第二次世界大战期间，以伦敦北面的布莱切利公园为工作地点的一组科学家和数学家， 制造了最早的全电子数字计算机之一：“巨人”。到1943年12月，这个包含了1500个真空管 的“巨人”开始运转了。它被以艾伦.图灵为首的小组用于破译德国用恩尼格码加密的无线 电报，他们的尝试大部分是成功的。 除此而外，在美国，约翰.阿塔纳索夫和克利福德.贝里早在1939年就在艾奥瓦州立学院
