Fiber to the Home(光纤到家)光纤到家（FTTH）是一个住宅的通信基础设施，光纤电缆运行所有的方式向用户。
经过多年的期待，各种部署光纤到户是最后出现在美国各地的社区虽然光纤到户是一种技术，它为本地接入市场的竞争动态有趣的影响。
光纤到户网络可以提供的带宽比目前现有的宽带技术的许多倍。
今天似乎每个人都想要的高速数据，可靠的语音服务，高质量的视频。
无论这些服务是由数字用户线（DSL）交付，电缆调制解调器或无线架构是微不足道的，只要服务是快速和可靠的。
FTTH使运营商能够提供多种通信和娱乐服务，包括高速互联网接入，广播，有线电视，直播卫星（DBS）电视，互动的双向视频服务。
此外，一个FTTH解决方案基于波分复用（WDM），允许更多的灵活性和适应性，进一步支持服务。
进一步支持服务的适应性。
在FTTH系统，在前端设备或是连接到公共交换电话网络（PSTN）唱DS-1和连接到ATM、以太网接口。
视频服务从有线电视（CATV）进入系统的头端或来至卫星饲料。
所有这些信号，然后合并成采用WDM技术单光纤传输通过无源光分路器的最终用户。
分路器通常放在离中心局（CO）约3000英尺。
分流比的范围可以从2到32的用户并没有在网络中使用任何活性成分。
然后将信号送到3个000英尺的家在一个单一的纤维。
一个理想的FTTH系统必须提供的所有服务用户的能力支付，如电路交换电话，视频服务、高速数据广播。
在家里，光信号转换成电信号的光电转换器（OEC）。
OEC把信号分成由最终用户所需的服务。
理想情况下，其将有标准的用户界面，提供所需的服务不集LLD盒。
这些接口包括电话RJ11插孔，RJ45接口的高速数据，和75欧姆同轴电缆端口的有线电视和卫星直播业务。
有关联的FTTH的几个优点，如下：这是一个被动网络，因此从有限无活性成分对最终用户这大大减少网络维护的成本和需求以及消除直流电源网络的需要。
它是一个单一的光纤到终端用户，提供各种服务与行业标准的用户界面，包括语音，高速数据，模拟或数字有线电视，星展，ANL视频。

Technology of Modern CommunicationText A: BluetoothBluetooth wireless technology is a short-range communications technology intended to replace the cables connecting portable（轻便的）and fixed devices while maintaining high levels of security.The key features of Bluetooth technology are robustness（稳健）, low power, and low cost .The Bluetooth specification defines a uniform structure for a wide range of devices to connect and communicate with each other.蓝牙无线技术是一种小范围无线通信技术，旨在保持高安全级的基础上，在便携式设备与固定设备之间实现无线连接。
蓝牙技术的主要特点是稳健，低功耗和低成本。
蓝牙规范定义了一个统一的结构，适用范围广的设备连接并相互沟通。
Bluetooth technology has achieved global acceptance such that any Bluetooth enable device, almost everywhere in the world, can connect to other Bluetooth enabled devices in proximity. Bluetooth enabled electronic devices connect and communicate wirelessly through short-range, ad hoc（特别）networks known as piconets Each device can simultaneously communicate with up to seven other devices within a single piconet. Each device can also belong to several piconets simultaneously. Piconets are established dynamically and automatically as Bluetooth enabled devices enter and leave radio proximity.蓝牙技术已取得全球认可，使得任何支持蓝牙的设备，几乎在世界各地，可以连接到其他支持蓝牙的邻近装置。

ResistorA resistor is a two-terminal electronic component that opposes an electric current by producing a voltage drop between its terminals in proportion to the current, that is ,in accordance wit h Ohm’s law :V=IR .The electrica l resistance R is equal to the voltage drop V across the resistor divided by the current I through the resistor. Resistors are used as part of electrical networks and electronic circuits.电阻器是一个二端口电子元件,电阻是阻止电流流动，通过按比例产生其端子之间的电压降的电流,也就是说,根据欧姆定律:V = IR。
电阻R等于电压降V除以通过电阻的电流I。
电阻作为电子网络和电子电路的一部分。
TransistorIn electronics, a transistor is a semiconductor device commonly used to amplify or switch electronic signals . A transistor is made of a solid piece of a semiconductor material , with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled current can be much larger than the controlling current, the transistor provides amplification of a signal. The transistor is the fundamental building block of modern electronic devices, and is used in radio, telephone, computer and other electronic systems. Some transistors are packaged individually but most are found in integrated circuits.在电子技术中，晶体管是一种，常用来放大或进行开关控制电子信号的半导体器。

Unit 6Part B1. Desktop systems allow remote users to share CAD files as well as other office documents created in spreadsheets, word processors, presentation packages, etc.桌面系统让远程用户能够共享计算机辅助设计档案以及其他一些制作在电子表格、文字处理器、图像程序包中的办公室文件。
3. At the World’s Fair 1964, AT&T demonstrated its first videophone, a desktop (or countertop)configuration that provided low quality images using analog technology.在1964年的世界博览会上，美国电话电报公司展示了其首款可视电话-一种桌面（或台式）机器。
因为使用的是模拟技术，它提供的图像质量不高。
5. Today, systems level implementers have to live within the constraints of standards-based compression algorithms, since standards are the foundation for interoperability, which in the communications field is absolutely necessary.如今，系统水平的操作者不得不受限于基于标准的压缩算法，因为标准时互用性的基础。
而在通行领域，互用性是极其重要的。
Part A1. The word “multimedia”is being used to describe a mixture of hardware, software and applications, with a consequent confusion in people’s mind as to what it is.“多媒体”一词被用来描述硬件、软件及应用的混合体。
这让人们在头脑里产生了“多媒体到底是什么”的疑惑。
the modern presentation of multimedia we now have the technology that can begin to move towards an ability, alreadyheld by the human being, in that by using computer technology, such as CD-ROM, not only can we bring together audio and visual images but also be interactive with other computer users.现在我们拥有接近某种人类能力的技术，即通过使用计算机技术，比如CD-ROM，我们不仅能够将视频图像和音频汇聚到一起，还能与其他的计算机用户进行相互交流。
多媒体现代内涵中包含了这一点。
7. The two levels are MPEG-1, which sets the provision of consumer quality of video and audio and MPEG-2,which sets the higher standards for professional, broadcast images and also looks to define high definition television(HDTV).这两个标准是MPEG-1和MPEG-2。
MPEG-1是用户质量的音频和视频标准；MPEG-2确定了更高的专业级广播图像标准并用以制定高清晰电视（HDTV）的标准。
Unit 5Part B1. During the first and second generations different regions of the world pursued different mobile phone standards, but are converging to a common standard for mobile multimedia called Third Generation(3G)that is based on CDMA technology.在第一和第二移动通信时代时间范围内的不同地区追求着各自不同的移动通信电话标准，但现在都在向基于CDMA技术的3G移动多媒体的共同标准靠拢。
4. Three generations of mobile phones have emerged so far, each successive generation more reliable and flexible than the last.迄今为止，已先后出现了三代移动电话，而且一代比一代更可靠、更灵活。
5. Digital mobile phone systems added fax, data and messaging capabilities as well as voice telephone service in many countries.数字移动电话系统除了能在众多国家内进行语音电话服务外，还增加了传真、数据、信息传递功能。
6. Following on the heels of analog and digital technology, the Third Generation will be digital mobile multimedia offering broadband mobile communications with voice , video, graphics, audio and other information.紧跟模拟和数字技术的步伐，第三代将会是数字移动多媒体技术。
它将会向宽带移动通信提供声音、视频、图片、音频和其他信息。
8. These are all derivatives of the World Wide Web aimed at connecting different communities of interest.这些都是万维网的衍生物，其目的在于能与不同的对象进行联系。
9. The data transmission rates will depend upon the environment the call is being made in it is only indoors and in stationary environments that these types of data rates will be available.数据传输速率将取决于呼叫环境，只有在室内和固定环境下才能达到这种速度。
● Generation（3G）facilitates several new applications that have not previously been readily available over mobile networks due to the limitations in data transmission speeds. 3G 促进了一些新的应用，而这些应用在先前的移动通信网上由于数据传输速率的限制不太容易实现。
Part A●(Global System for Mobile communications )全球移动通信系统。
基站收发器BSC 基站控制器MSC 移动交换中心PSTN 公共交换的电话网络5. The speed and rapidity with which the personal communications revolution takes place is, unlike fixed transmission systems, highly dependent on technology and communications standards.与固定通信系统不同，个人通信的快速发展在很大程度上依赖于技术和通信标准的发展。
6. For mobile the problem is far more complex, with the need to roam creating a need for complex networks and systems.对于移动通信来说，问题要复杂得多，因为漫游业务的开展需要更加复杂的网络和系统。
7. The second generation is very much dominated by the standard first set out in Europe by the Group Special Mobile(GSM) committee, which was designed as a global mobile communications system.第二代移动通信系统在很大程度上是由欧洲特别移动委员会首先制订的标准所决定的，被设计成为一种全球移动通信系统。
Unit 4Part B7. RJ stands for Registered Jack , implying that the connector follows a standard borrowed from the telephone industry.RJ标准就是寄存器插口，即一种来自于电话工业的标准。
8. It transmits light rather than electronic signals eliminating the problem of electrical interference.它是传输光信号而不是传输电信号的电子接口，因此避免了电干扰的问题。
Part A(Deutsche Industries Norm):德国工业标准ＤＩＮtype connector 是一种由德国开发的连接器。
5. Most NICs are internal, with the card fitting into an expansion slot inside the computer.大部分的网卡都是内置的，这张卡插入到计算机内部的一个扩展槽中。
6. While bridges know the addresses of all computers on each side of the network, routers know the addresses of computers, bridges and other routers on the network.虽然网桥知道网络中任何一处所有计算机的地址，但是路由器知道网络中所有的计算机、网桥和其他路由器的地址。
