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.

计算机专业英语的课文与翻译

Unit 8 Computer Networking Text 1 Data Communications The end equipment can be computers, printers, keyboards, CRTs, and so on.They are either generates the digital information for transmission or uses the received digital data. This equipment generally operates digital information internally in word units. DTE is data terminal equipment. A station controller (STACO)is the corresponding unit at the secondaries. At one time, the DTE was the last piece of equipment that belonged to the subscriber in a data link system. Between the DTEs, first is the modem, and then is the communications equipment. The communication equipment is owned and maintained by Telco. Data communications equipment (DCE) accepts the serial data stream from the DTE. And DCE converts it to some form of analog signal suitable for transmission on voice-grade lines. At the receive end, the DCE performs the reverse function. It converts the received analog signal to a serial digital data stream. The simplest form of DCE is a modem (modulator/demodulator) or data set. At the transmit end, the modem can be considered a form of digital-to-analog converter.While at the receive end, it can be considered a form of analog-to-digital converter. 参考译文 数据通信 终端设备可以是计算机、打印机、键盘、CRT等。它们可以生成要发送的数字信息,也可以使用所接收的数字数据。这种设备通常在内部以字为单位处理数字信息。 DTE一般称为数据终端设备。辅助设备一方的相应设备是工作站控制器(STACO)。同时,DTE也是数据链路系统中属于用户端的最后一个设备。在两个DTE之间,先是调制解调器,接着是属于Telco电话公司维护的通信设备。数据通信设备(DCE)从DTE接收串行数据流,并将其转换成适合于在语音线路上发送的某种模拟信号形式。在接收端,DCE完成相反的功能,把接收到的模拟信号转换成串行数字数据流。最简单的DCE是调制解调器或数据传送机。在发送端,调制解调器可以视为一种数/模转换器,而在接收端则可视为一种模/数转换器。 Text 2 Architecture of Computer Networks Computer network is a complex unit, it consists of two or more connected computing units. It is used for the purpose of data communication and resource sharing. Design of a network and its logical structure should comply with a set of design principles. They include: the organization of functions, the description of data formats and procedure. In the following two sections we will discuss two important network architectures, the OSI reference model and the TCP/IP reference model. (1)the OSI reference model The OSI (open systems interconnection) model was created by the ISO. This model is a foundation for comparing protocols; However, more protocols deviate from the rules set up by the OSI model. The OSI model has seven layers. Note that the OSI model itself is not a network architecture.

第9单元电子商务 第一部分听力和对话 对话:使用在线支付服务保护消费者的隐私 (Henry非常兴奋地在一家网上书店中发现了自己期待已久的图书,但是当得知系统要 求通过账号支付时,他犹豫了。) Henry: 最近互联网上信用卡账号的公然欺骗无疑为我们敲响了警钟。在进行在线交易时,我们并不知道要把自己的信用卡账号告诉谁。 Mark: 也许你可以使用第三方支付服务来保证在线支付更简单、更安全。 Henry: 什么是第三方支付服务? Sophie: 简单地说,在使用第三方支付服务时,你可以把自己的资金转移到一个在线账号中,然后从那个账号中进行支付。这样就不用把自己的真实信用卡或银号账户信息暴露在网络上了。 Henry: 这种方法听起来更安全。有哪些第三方支付服务可以方便地使用? Mark:在美国最受欢迎的服务是eBay公司掌控的PayPal,但也有一些其他的服务,如https://www.sodocs.net/doc/635797368.html, Payment等。以最简单的支付为例,例如在线拍卖或简单的网站销售,销售商只需要向买家提供他们的E-mail地址,而买家向销售商的PayPal账号进行适当的支付。Henry: 我明白了。 Sophie: 做出选择之后,建议你留意选择更加安全服务的一些细节。 Henry: 什么是更加安全服务的一些细节呢? Sophie: 首先,阅读隐私政策,并确保自己同意其中的条款。如果不同意,可以继续选择其他的安全服务。此外,确认网站符合权威部门规定的特定的标准(查验同意的盖章)。这些的确都是非常重要但是有时被用户忽略的步骤。 Mark: 当使用第三方支付服务时,Henry,请记住千万不要回复来自第三方支付服务机构发送的要求确认如密码或其他私人身份识别信息等与账号细节相关的电子邮件。这些邮件很可能是身份盗窃骗局,如网络钓鱼。 Henry: 那么,怎样才能更安全地确认或处理我的账号细节呢? Sophie: 如果需要确认或更新账号信息或者修改密码,我建议你可通过个人书签或者在浏览器中直接输入支付服务网站的URL来访问相应的网站。 Henry: 如何进一步确认卖家能够提供有效的支付服务? Mark: 你可以通过查看卖家在几个月或更长的时间内是否为支付服务机构的有效成员来确定。有些网站还允许用户查看卖家的评价,虽然这些评价并不能作为保证,但是却是非常有用的信息。 Sophie: 切记,Henry,不要用自己的账号把资金转移到一个你不认识的人的账号里。这可能是一种高级的资金诈骗。还有,当你要购买一些诸如珠宝或者计算机等昂贵的物品时,尤其是在节假日或者商铺中售出的物品时,需要多加小心。 Henry: 好的。现在我对进行安全在线支付更加有信心了。非常感谢你们的见议。 练习

大学实用计算机英语教程翻译-吕云翔-Unit 5

Unit 5 Section A Software Design (软件设计) Design is defined in [IEEE610.12-90] as both “the process of defining the architecture, components, interfaces, and other characteristics of a system or component ” and “the result of that process.” Viewed as a process, software design is the software engineering life cycle activity in which software requirements are analyzed in order to produce a description of the software ’s internal structure that will serve as the basis for its construction. More precisely, a software design (the result) must describe the software architecture -- that is how software is decomposed and organized into components -- and the interfaces between those components. It must also describe the components at a level of detail that enable their construction. Software design plays an important role in developing software: it allows software engineers to produce various models that form a kind of blueprint of the solution to be implemented. We can analyze and evaluate these models to determine whether or not they will allow us to fulfill the various requirements. We can also examine and evaluate various alternative solutions and trade-offs . Finally, we can use the resulting models to plan the subsequent development activities, in addition to using them as input and the starting point of construction and testing. In a standard listing of software life cycle processed such as IEEE/EIA 12207 Software Life Cycle Processes [IEEE 12207.0-96], software design consists of two activities that fit between software requirements analysis and software construction: Software architectural design (sometimes called top level design): describing software ’s top-level structure and organization and identifying the various components. Software detailed design: describing each component sufficiently to allow for its construction.

计算机英语_学生用书(第二版)姜同强_翻译

翻译:计算机英语(第二版)姜同强——第一章 第1 章计算机系统概述 数字计算机也称为电子计算机或计算机.它无处不在.很难发现有哪个领域没有使用计算机.在本章中.我们将介绍数字计算机、数据类型、计算机的发展和计算机分类, 1 . 1 数字计算机 数字计算机是处理各种计算任务的数字系统.“数字”的意思是计算机中的信息可由具有部分离散值的变量来表示,这些离散值的内部处理是由具有部分离散状态的部件完成的.例如.十进制数字O , l , 2 ,… 9 .即提供了10 个离散值。第一台电子数字计算机产生于20 世纪40年代末,它主要用于数值计算,那时的离散元素即为数字.为了进行数值计算而产生了数字计算机.实际上.如果只使用两种状态.数字计算机的性能将更可靠。因为部件的物理约束和人们的逻辑处理需要.所以数字计算机使用具有两种值的离散数据.这种数据称为二进制。 数字计算机使用只有数字O 和l 的二进制数据系统.一个二进制数字称作位.在数字计算机中用一组二进制表示信息。应用各种编码技术.一组二进制数字不但可以表示二进制数据,而且还可以表示其他离散符号.如十进制数字或字母表中的字母.例如ASCII是用7 位二进制数字表示一个字符。通过合理使用二进制组合和各种编码技术.可产生用于完成各种类型计算的一系列指令。与基数为10 的十进制数相比.二进制数的基数为2 .使用了数字O 和1 .与一个二进制数等值的十进制数可以扩展为包含更多位的二进制数. 计算机系统是由硬件系统和软件系统组成的,硬件系统由看得见、摸得着的物理设备构成.如磁盘和屏幕。软件系统是管理计算机的无形“控制”,是运行在计算机中的所有程序,程序是指令的集台,它告诉硬件应该做什么,通常将计算机硬件分为3 个主要部分:输入和输出设备(I/O 设备)、中央处理器(CPU)和存储器。在第2 章中对硬件部分进行详细介绍.软件可以按其用途分类。应用软件是为诸如会计、娱乐和工程领域之类的处理任务而设计的,如果玩过计算机游戏或用字处理软件输入入过文件内容.则用户已经具有使用应用软件的体验。另一方面.系统软件控制计算机系统,它不仅包括专业人员用于创建应用软件的复杂程序.而且还包括用于启动计算机和提供给其他程序使用的管理程序.这部分内容将在第2 章和第6 章中详细介绍, 1 . 2 数据类型 数字计算机中的二进制信息存储在存储器或处理器的寄存器中。寄存器的内容为数据或控制信息。控制信息为一位或多位.用于表明控制信号的顺序.这些信号用于处理其他寄存器的数据.数据是数字和其他二进制代码信息.通过处理这些数据得到所需的计算结果.下面介绍在数字计算机最常用的数据类型和各种数据类型在计算机的寄存器中如何以二进制代码的形式表示. 数字计算机寄存器中的数据可分类如下; .数值数据常用来表示整数.n位无符号整数.其值的表示范围为O ~-l ;n位带符号整数.其值的表示范围为- ~-1。这两种格式的数据可以用于算术运算。有些数值数据不能表示为整数。这些数值在计算机中用浮点格式表示.典型的如小数部分。计算机中有专用于浮点数的寄存器和指令。 .布尔值TRUE 和FALSE 经常被被使用.这使它们有自己的数据类型一一布尔型和汇编语言指令.常用0 值表示FALSE .用非0 值表示TRUE 。布尔汇编语言 指令可以对布尔数据执行逻辑操作。与逻辑指令每位都产生操作结果不同,布尔指令只产生一个结果。下面举例来说明它们的不同,若A=0000 0010 , B =0000 0001,则二进制数据的逻辑与运算的给果为0000 0000;然而,如果它们是布尔值,因为它们均为非O ,所以A 和B 均为TRUE ,对它们进行布尔与运算给果为TRUE ,用非O 值表示。 .计算机也可处理字符型数据。字符型数据用ASCII、EBCDIC 、UNICODE或其他字符编码标准编码后的二进制数据进行存储。计算机能将若干字符连成串,用一些字符代替其他字符或另行处理字符串,而不是用算术方法或逻辑方法处理字符。有些汇编语言指令集中包含了直接处理字符数据的指令,而另一些汇编语言指令集中则运用其他指令构成例程来达到相同的结果。 1.3 计算机的发展 第一台大型电子计算机是电子数字模拟计算机(ENIAC),它诞生于1946 年.从此计算机经历了4 个发展年代或阶段。每一年代的特点是:与上一年代相比,体积更小,费用更低。 1 .第一代(1944-1958)
