Reading Materials Passage Ⅱ

Multimedia Personal Computer

Syntax

1. The requirements for an MPC are described in detail in Microsoft’s Multimedia PC Specification Version 1.0. Here are the key elements of the specification:

【分析】此句为被动语态，其中key这一词在该句中为形容词，译为“关键的”；specification的意思是“规范，说明书”。

【句意】Microsoft公司的《多媒体PC机规范1.0版》一书对MPC机进行了详细描述。以下是此规范的要求：

2. BASE SYSTEM: a Windows-capable system with a 10-MHz 286 or faster CPU; at least 2MB of RAM; a 30 MB or larger hard disk; a

3.5-inch 1.44 MB floppy drive; a 101-key keyboard; a two-button mouse; and parallel, serial, and joystick ports.

【分析】该句中parallel的意思是“并行”，serial的意思是“串行”，joystick port的意思是“控制杆端口”。

【句意】基本系统：一个能运行Windows的系统。它采用10MHz时钟的286或速度更快的CPU；至少有2MB的RAM；30MB或更大的硬盘空间；3.5英寸1.44MB的软盘驱动器；101键盘；两按钮的鼠标器以及并行、串行的控制杆端口。

3. CD-ROM: a CD-ROM drive that transfers at least 150KB of data per second without taking up more than 40 percent of the CPU’s attention, play CD audio, and has an average access time of 1 second or less.

【分析】without 介词，意思是“没有，不，（表条件）如果没有, 要没有”，通常表示否定。

【句意】CD-ROM：要求CD-ROM光驱的数据传输速率至少为每秒150 KB，不能占用40%以上的CPU时间，能播放CD，平均存取时间为1秒或更短。

4. AUDIO: a sound board with 8-bit, 11.025-kHz sampling and 22.05-kHz playback; a synthesizer capable of playing eight notes simultaneously using five different sounds; a mixer to combine CD audio, sampling, and synth; a microphone input; and MIDI in, out, and thruports.

【分析】playback的意思是“录音重放，重放”在该句中指声音回放；simultaneously 的意思是“同时地”；synthesizer和synth这两个词的意思相同，均指“综合者，[电子]合成器”。

【句意】音频功能：一块8位的、11.025kHz取样和22.05kHz回放的声卡；能同时放8个使用5种不同音色的音律的合成器；能把光盘音频、取样和合成声音混合起来的混声器；麦克风输入；MIDI（乐器数字接口）输入、输出和通路。

5. Every new technology has its own buzzwords, and sorting them out can be real detective work. The following is two jargons of MPC.

【分析】buzzword名词意思是“专门用语，术语”，与某一特定领域或组织相联系，主要用于给外行之人加深印象的听起来重要的单词或短语；词组sort… out的意思是“分类出”；jargon的意思是指“行话，术语”。

【句意】每一种新技术都有它自己的术语，将它们进行分类是一项非常精细的工作。下面是MPC的两个术语。

6. FULL-MOTION VIDEO: Full-motion video is digitally recorded video played back at the broadcast standard of 30 frames per second, or close enough to that speed so the video appears smooth rather than jerky.

【分析】rather than的意思是“胜于”。

【句意】全运动图像：全运动图像是以数字方式记录的视频图像，以每秒30帧的电视广播标准或者非常接近于此的速度重现图像，因而这些视频图像看上去很自然，没有跳跃感。

7. MIDI: MIDI is short for Musical Instrument Digital Interface, a standard specification developed by music synthesizer manufacturers. The concept of being able to control several instruments from one keyboard has grown into a method for putting musical instruments, tape recorders, VCRs, mixers, and even stage-lighting under the control of a single computer.

【分析】under the control of译为“在……的控制之下”。

【句意】MIDI：MIDI是乐器数字接口的缩写。它是由音乐合成器制造商开发的标准规范。从一个键盘能控制几个乐器的想法已变为现实，它能把乐器、磁带录音机、录像机、混声器、甚至舞台灯光等置于单台计算机的控制之下。

计算机英语第三版课文翻译

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

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.

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.
