网络工程师英语词汇表1网络工程师词汇表21.GB Ethernet（兆位以太网）一种新的高速以太网，由IEEE802.3 工程规定。

带宽1 0 0 0 M b p s，虽然可以运作在小段的 U T P（非屏蔽双绞线），但通常运行在光纤介质上。

1 0 B a s e2 一种以太网，根据 I E E E 8 0 2 . 3标准，使用铜缆作为介质，为总线拓扑，1 0 B a s e 2也叫细网或细以太网，它的名字来源于它以 1 0 M b p s 的速度传输数据（所以叫“1 0 B a s e”）和它的网段最大长度为 1 8 5米，大约2 0 0米（所以叫“ 2”）。

1 0 B a s e 5 最初的以太网标准，它使用总线拓扑和粗同轴电缆，也叫粗网或粗以太网。

它的名字来源于它以 1 0 M b p s的速度传输数据（所以叫“ 1 0 B a s e”）和它的网段最大长度为 5 0 0米（所以叫“ 5”）。

1 0 B a s e T 一种以太网类型，它使用双绞线，星形 -总线拓扑或树形拓扑。

以 1 0 M b p s传输数据（所以叫“ 1 0 B a s e”）和它需要双绞线（ t w i s t e d - p a i r）作为介质（所以叫“ T”）。

1 0 0 B a s e T I E E E 8 02 .3 u定义的一种新的以太网标准，它使以太网在不作大的投资和结构改变的情况下能把局域网的传输速度提高到 1 0 0 M b p s。

1 0 0 B a s e T在星形-总线拓扑或树形拓扑中使用基带传输，像 10Base T一样，“T”代表使用双绞线。

1 0 0 B a s e T X 100Base T技术的一种，它通过以 1 0倍的速度传送信号并且减少数字脉冲间隔和工作站用于 C S M A / C D的等待和侦听时间来达到 1 0 0 M b p s的传输速度，它要求 5类U T P（非屏蔽双绞线）。

1.1 The Invention of the ComputerIt is hard to say exactly when the modern computer wasinvented. Starting in the 1930s and through the 1940s, a numberof machines were developed that were like computers. But mostof these machines did not have all the characteristics that weassociate with computers today. These characteristics are thatthe machine is electronic, that it has a stored program, and thatit is general purpose.很难确切地说现代计算机是什么时候发明的。

从2 0世纪3 0年代到4 0年代，制造了许多类似计算机的机器。

但是这些机器大部分没有今天我们所说的计算机的所有特征。

这些特性是：机器是电子的，具有储存的程序, 而且是通用的。

1.1 The Invention of the ComputerOne of the first computerlike devices was developed in Germany byKonrad Zuse in 1941. Called the Z3, it was general-purpose, stored-program machine with many electronic parts, but it had a mechanicalmemory. Another electromechanical computing machine was developed byHoward Aiken, with financial assistance from IBM, at Harvard Universityin 1943. It was called the Automatic Sequence Control Calculator Mark I, or simply the Harvard Mark I. Neither of these machines was a true computer, however, because they were not entirely electronic.第一个类似计算机的装置之一是1 941年由德国的K onradZuse研制的，叫做Z 3,它是通用型储存程序机器，具有许多电子部件，但是它的存储器是机械的。

运维涉及到的英语词汇1. IntroductionIn the field of operation and maintenance (O&M), there are various English words and terms that are commonly used.

网络工程师专业英语Network Engineering is a field that combines computer science and engineering to design, implement, and maintain computer networks. As a network engineer, professionals are responsible for analyzing and evaluating network systems, identifying solutions to problems, and providing technical support to ensure the smooth operation of networks.To become a network engineer, one should have a strong foundation in computer science and engineering principles. It is essential to have knowledge of networking protocols, hardware, and software. Network engineers are proficient in programming languages such as C++, Java, and Python, as well as network administration tools.A network engineer's job involves various tasks, including designing network architecture, configuring routers and switches, implementing security measures, and monitoring network performance. They work closely with clients and other professionals to understand their needs and provide solutions that meet their requirements. Moreover, network engineers also play a crucial role in troubleshooting and resolving network issues efficiently and effectively.The field of network engineering is continuously evolving due to the rapid advancement of technology. Network engineers must stay updated with the latest trends and innovations in the industry. They need to be familiar with emerging technologies such as cloud computing, software-defined networking, and virtualization. Additionally, network engineers must possess problem-solvingskills and be able to adapt to new challenges and changes in the network environment.Effective communication is another important skill for network engineers. They must be able to communicate technical information to non-technical individuals and work collaboratively within a team. Additionally, network engineers should have strong analytical and organizational skills to efficiently manage and document network resources and configurations.In conclusion, network engineering is a specialized field that requires a strong knowledge of computer science and engineering principles. Network engineers play a critical role in designing, implementing, and maintaining computer networks. They must stay updated with emerging technologies and possess strong problem-solving, communication, and organizational skills.+网络工程涉及到网络系统的设计、实施和维护，结合了计算机科学和工程学的知识。

09下半年网络工程师英文真题、译文及答案Routing protocols use different techniques for assigning（71）to individual networks．Further, each routing protocol forms a metric aggregation in a different way. Most routing protocols can use multiple paths if the paths have an equal（72）.Some routing protocols can even use multiple paths when paths have an unequal cost.In either case,load（73）can improve overall allocation of network bandwidth．When multiple paths are used,there are several ways to distribute the packets. The two most common mechanisms are per-packet load balancing and per-destination load balancing.Per-packet load balancing distributes the（74）across the possible routes in a manner proportional to the route metrics,Per-destination load balancing distributes packets across the possible routes based on（75）.（71）A. calls B. metrics C. links D. destinations（72）A. user B. distance C. entity D. cost（73）A. bracketing B. balancing C. downloading D. transmitting（74）A. destinations B. resources C. packets D. sources（75）A. destinations B. resources C. packets D. sources参考译文各种路由协议使用不同的技术来为网络赋予度量值。
