Step 3. Leading in a short introduction to Network Devices Network devices include all computers, media, interface cards and other equipments needed to perform data-processing and communications within the network. Let ’s look at some typical network devices. Step 4. Analyzing the structure of the complex sentences 1. NICs are considered Layer 2 devices because each individual NIC throughout the world carries a unique code, called a Media Access Control (MAC) address. 2. Repeaters are networking devices that exit at Layer 1, the physical layer, of the OSI reference model. Step 5. Memorizing and mastering the following key sentences in the text. 1. The network interface card provides the physical connection between the network and the computer workstation.

2. NIC is a major factor in determining the speed and performance of a network.

3. One of the disadvantages of the type of cable that we primarily

use, CAT5 UTP, is cable length.

4. The repeater electrically amplifies the signal it receives and

rebroadcasts it.

5. Generally speaking, hub is used when referring to the device that serves as the center of a network

6. The difference is the number of cables that connects to the device.

7. Whereas a repeater receives signal on one port and repeats it on the other, a hub

receives signal on one port and transmits it to all other ports.

Doctors of that time knew very little about causes of sickness or ways of preventing it. Thousands of men in poor health became soldiers. Hundreds of others had never had childhood diseases. Many of these soldiers could not withstand the epidemics of measles, mumps, and whooping cough that went through the camps. Army life was hard. Soldiers got few fruits or vegetables. There was no milk unless they happened to find a cow. Neither their clothes nor their shelters protected the troops from rain, snow, and cold. Sickness and disease were spread by insects, rats, and impure drinking water. Often the men drank straight from muddy streams. Gunshot wounds were serious, as in any war,

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

Robot Competition From 11th to 13th October 2013, these three days are special for my teammates and me. I took part in the fifth Robot Competition of Anhui province. After continuous efforts, we got the third prize in the end. In April 2013, this competition was announced in our class by Mr He. In that moment, many students registered for the competition. After hardly training, there were only fifteen students remaining. We were divided into five teams. Each included three people. There were three teams taking part in wheel type robot competition (or named intelligent car). And the other two majored in dancing robot. My two roommates and I engaged in the designing of robot dance. We controlled the robots by program. But the program was programmed in BASIC, which is a high level programming language. The problem was that we had never touched to that language besides C or C++. So, we must learn the language before designing the action. It seemed difficult but we had never lost our courage. After seeking enough data from the Internet and the library, we spent about a few weeks to learn it. When we felt the fundamental grammar was easy, we began to design the dancing action. That was the most important and most difficult part. We spent much time on

1.英语学术论文的语言风格特点就（知人方能论世） 为什么我们会读不懂SCI上面的文章呢？ 第一，由于SCI里面出现的专业词汇一般都是出现在特定领域，一类是一词对应于一意，另外一类则是一词多义。 其次，名词化结构则是另外另外一个普遍出现的现象，可以看到，复合名词，加前缀和后缀，以及省略现象可谓是漫山遍野，因为文体要求行文简洁、表达客观、内容确切、信息量大、强调存在的事实，一般文章不会夹杂着太多主观看法。 最后，大量使用长句和定语从句SCI论文发表中大量使用长句和定语从句，在论证上起到连接信息和强调信息的作用。广泛使用被动语态SCI论文发表中侧重叙事推理，强调客观准确，第一、二人称使用过多，会造成主观臆断的印象。因此尽量使用第三人称叙述，采用被动语态。名词作定语和缩写词使用频繁SCI论文发表中要求结构紧凑、行文简炼，缩写词和名词作定语的频繁使用，增大了信息密度，简化了句型。 如果我们能逆向思维，转换个角度去看文章，如果你要发表一篇SCI论文，你会怎么去构造你的行为，你如何组织你文章的逻辑，特别是用词方面，口语和一些狸语在一般

情况不应该出现在文章中。还有些中式英语也会极大地影响我们的阅读，例如说足球比赛，可不是我们想象中的football match （之前有次演讲说，英语里面不能有2个名词的情况，在此就举了个例子bicycle man），而应该做football play亦作soccer play。 2.翻译是一门艺术，从某种意义上来讲是没有标准答案的。 这里本人想要想要阐述这样一种观点，翻译是一个不断精进的过程，翻译最初的目的即是为了实现语言之间的一个互相沟通，然而不同的人对一句话，应该会有着不同的理解。这也就有了译者极大的自由发挥性，但是译者必须准确理解原文的基础之上的。 有三个字可以高度概括翻译的精髓“信，达，雅”，想必大家都应该听过。”“信”指意义不背原文,即是译文要准确,不歪曲,不遗漏,也不要随意增减意思；同样可以举个例子？This is a pan in my hand （请问如何翻译呢？） “达”指不拘泥于原文形式,译文通顺明白;这里就涉及到一个直译和意译的关系啦，否则就会出现像bicycle

计算机专业英语作业： 1、请将视频“什么是电脑硬件”中所述内容用英文表示。 For most people, computers are becoming a part of real life, the film will help you konw how it works. Their interior looks very complicated, but if the decomposition of parts, you will see a simple side of computers , This is《computer hardware in Plaining English 》,you see them, they are coming all shapes and sizes,but its work in some ways. In fact, if you can see their internals of computers, You will find that they all have the basic parts,the haddwares,do large part of the works in the computers.to explan,let’s look at some things you know ,like a house.what a great thing in the house is you have full space to put all the iterms.in fact ,many houses have basements.The basement is a good place to store debris.Basement, the more you can store.The same principle applies to computers.We need not boxes and bicycles, but photos, music, documents and https://www.wendangku.net/doc/ba17471831.html,plete this task in the computer hard drive rather than in the basement, a computer hard drive, holds all your files will be used later, like basements, like the larger hard drive, the more things you can store. Basement is not perfect, going to the basement to take the things you need to spend much time, maybe put a cupboard on the ground floor can help you solve this problem, you can quickly get the items you want, although the cabinet can not put too many items, at least you do not always go to the basement, in the computer too, The computer can not quickly access to the data stored in the hard disk, because the computer go a long way to gain access to the hard disk data. In the computer memory (RAM) is like a cupboard, RAM's full name is called [random access memory], which allows the computer to access data more quickly and, of course, it also means that the operation of RAM to make your computer faster , but this cupboard (RAM) has a drawback, the memory will be cleared of stored data When every time you restart, of course, to make the house a variety of household appliances can operate at the appropriate time, you must have an Explorer to help you manage these appliances, if the weather is too hot , you maybe need to open the air conditioner to adjust the temperature, when it is dark, you need to turn on the lights. Computers, too, must have a bit Explorer to ensure that all other parts are functioning properly, the Explorer is the processor (CPU), small size of the processor, like a computer exclusive (in charge), it will send and receive information and to assist the software to complete the work. The faster the processor, the faster execution speed of the computer would be, so, let us revisit. Hard drive, like a basement, it can store the information you need. Memory, like a cupboard, which can increase data access speed. Processor, like the Field Explorer, always able to complete the work that we deliver, but also to ensure the normal operation of the various parts. Next time, when you use the computer, think about plain English in the host computer's computer hardware what happened, the various parts of computer hardware complement each other, to help you do all the things I Common Craft's Lee LeFever, "Computer hardware of Plaining English "The film recorded by me, if you need a higher quality video, or need to use the authorization of the film, please contact me https://www.wendangku.net/doc/ba17471831.html, website. 2、请将以下英文翻译为中文。

Firstly, there is maintenance to repair software faults. Coding errors are usually relatively cheap to correct; design errors are more expensive as they may involve rewriting several program components. Requirements errors are the most expensive to repair because of the extensive system redesign that may be necessary. Secondly, there is maintenance to adapt the software to a different operating environment. This type of
