A general purpose computer has four main components: the arithmetic logic unit (ALU), the control unit, the memory, and the input and output devices （collectively termed I/O). These parts are interconnected by buses, often made of groups of wires.
Inside each of these parts are trillions of small electrical circuits which can be turned off or on by means of an electronic switch. Each circuit represents a bit (binary digit) of information so that when the circuit is on it represents a “1”, and when off it represents a “0” (in positive logic representation). The Circuits are arranged in logic gates so
that one or more of the circuits may control the state of one or

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,

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

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.doczj.com/doc/9f18787740.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.doczj.com/doc/9f18787740.html, website. 2、请将以下英文翻译为中文。

He who practices a lot will master the skill more quickly tha n he who seldom or hardly practices. For example, whe n we lear n En glish, we have to lear n grammar, words, expressi ons and so on. The most importa nt thi ng may be how to put what we have lear ned into practice. If you only lear n the grammar rules by heart and dofi t do eno ugh exercises, it is certain that you can7 t understand them perfectly. But if you practice a lot, maybe you will un dersta nd them more deeply and you can find some good methods of applying them. Memorizing English words whenever time permits, we can easily memorize them and can even find a way to memorize them more quickly. There is ano ther example. A famous sin ger can sing very welt. Of course, his tale nt is very importa nt, but practice is n ecessary. It is n ecessary to practice tomake the sin ger sing better and better. It is evident that practice is important for everybody. If you want to improve your study and work, you should remember that practice makes perfect.

Chapter1 1-11.What are two reasons for using layered protocols? (请说出使用分层协议的两个理由) 答：通过协议分层可以把设计问题划分成较小的易于处理的片段。分层意味着某一层的协议的改变不会影响高层或低层的协议。 1-13. What is the principal difference between connectionless communication and connection-oriented communication? (在无连接通信和面向连接的通信两者之间，最主要的区别是什么？) 答：主要的区别有两条。 其一：面向连接通信分为三个阶段，第一是建立连接，在此阶段，发出一个建立连接的请求。只有在连接成功建立之后，才能开始数据传输，这是第二阶段。接着，当数据传输完毕，必须释放连接。而无连接通信没有这么多阶段，它直接进行数据传输。 其二：面向连接的通信具有数据的保序性，而无连接的通信不能保证接收数据的顺序与发送数据的顺序一致。 1-20. A system has an n-layer protocol hierarchy. Applications generate messages of length M bytes. At each of the layers, an h-byte header is added. What fraction of the network bandwidth is filled with headers? (一个系统有n层协议的层次结构。应用程序产生的消息的长度为M字节。在每一层上需要加上一个h字节的头。请问，这些头需要占用多少比例的网络带宽) 答：hn/(hn+m)*100% 1-28. An image is 1024 x 768 pixels with 3 bytes/pixel. Assume the image is uncompressed. How long does it take to transmit it over a 56-kbps modem channel? Over a 1-Mbps cable modem? Over a 10-Mbps Ethernet? Over 100-Mbps Ethernet? (一幅图像的分辨率为1024 x 768像素，每个像素用3字节来表示。假设该图像没有被压缩。请问，通过56kbps的调制解调器信道来传输这幅图像需要多长时间？通过1Mbps的电缆调制解调器呢？通过10Mbps的以太网呢？通过100Mbps的以太网呢?) 答：The image is 1024*768*3 bytes or 2359296 bytes.This is 18874368 bit. At 56,000 bits/sec, it takes about 337.042 sec. At 1,000,000 bits/sec, it takes about 18.874 sec. At 10,000,000 bits/sec, it takes about 1.887 sec. At 100,000,000 bits/sec, it takes about 0.189 sec. Chapter2 2-2. A noiseless 4-kHz channel is sampled every 1 msec. What is the maximum data rate? (一条无噪声4kHz信道按照每1ms一次进行采样，请问最大数据传输率是多少？)
