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)。
Task 1James: Dell Company. How can I help you?Jane: Oh, hello. This is Jane. My computer doesn’t work. And I think I have to reinstall the operating system. I prefer Windows Vista. Could you walk me through the steps? James: Sure. Our engineers in the Technical Support Department can help you. I’ll put you through.Just a second, please.Jane: OK. Thank you.Key Words:1. reinstall / installation2. VISTA: Viewing Instantly Security Transactions AutomaticallyExpressions:Walk sb through the stepsTask 2Chris: Technical Support Department. This is Chris. How can I help you?Jane: Hello. This is Jane. I need to install Windows Vista on my computer.Chris: Then first you need to plan your installation. Have you checked system requirements, hardware and software compatibility, and determined disk partitioning options?Jane: Yes. They shouldn’t be problem.Chris: So, insert your Windows Vista installation disk into the drive and reboot your computer. It’ll boot directly into Graphical User Interface mode.Jane: OK. It’s done.Chris: Press the Install Now button, accept the license terms and then press the Custom Installation button.Jane: That sounds easy.Chris: Then you just need press on the Next button. This will take some time.Jane: All right. Now the computer is automatically rebooting Seems it’ll be a long wait for you. I guess I know what to do next. So I’ll just hang up. Thanks a lot.Chris: Sure. Call us if there’s any problem.Key Words:patibility n 通用性,兼容性2. determine vt & vi. I haven't determined yet.我还没有决定呢。

第1套ISDN,which stands for Integrated Services Digital Network, is a system of digital phone connectio ns, which has been available for over a decade.This system allows data to be transmitted simultane ously across the world using (1) digital connectivity.With ISDN,voice and data are carried by bear er channels occupying a bandwith of (2) (bits per second).Some switches limit B channels to cap acity of 56 Kbps.A data channel (3) handles signaling at 16Kbps or 64Kbps,depending on (4) .No te that,in ISDN termi nology,”k” means (5),and not 1024(2^10) as in many computer applications ;therefore,a 64Kbps channel carries data at a rate of 64000bps. A new set of standard prefixes has recently been created to handle this. Under this scheme,”K”(Kilo) means 1000(10^3),”M” (Mega) means 1000000(10^6),and soon ,and “Ki”(Kibi) means 1024 (2^10),”Mi” (Mebi) means 1048576 (2^20).and soon。
