试题解析

以太网交换机

以太网交换机是基于以太网传输数据的交换机,以太网采用共享总线型传输媒体方式的局域网。以太网交换机的结构是每个端口都直接与主机相连,并且一般都工作在全双工方式。交换机能同时连通许多对端口,使每一对相互通信的主机都能像独占通信媒体那样,进行无冲突地传输数据。

带宽

带宽应用的领域非常多,可以用来标识信号传输的数据传输能力、标识单位时间内通过链路的数据量、标识显示器的显示能力。1. 在模拟信号系统又叫频宽,是指在固定的时间可传输的资料数量,亦即在传输管道中可以传递数据的能力。通常以每秒传送周期或赫兹(Hz)来表示。2. 在数字设备中,带宽指单位时间能通过链路的数据量。通常以bps来表示,即每秒可传输之位数。

Practice 1  The greenhouse effect causes trouble by raising the temperature of the planet. The  1 rise is not very much,but the Earth’s ecosystem is very weak,and small changes can have large effects.  It has been believed that this 2 of one degree will happen by the year 2025. This could probably  3 the North American corn belt, which produces much of the world’s grain, 4 to much higher food prices,and even less food for the Third World than they already have. However,it would also mean that some countries which are further north would be able to  5 crops they had never been able to before,although there is less land as you move north from the corn belt.  The other serious worry is that rising sea levels from the melting of the polar ice could  6 flood many countries. A rise in sea levels of one meter,which many expels are  7 by the year 2100 (and some as soon as 2030),would flood 15 percent of Egypt,and 12 percent of Bangladesh. The Maldives in the Indian Ocean would almost  8 disappear. Most of the countries which would suffer most from a rise in sea levels are the poor  9  states,so the islands in the Caribbean,South Pacific,Meditertgiiean and Indian Ocean have formed the Alliance of Small Island States,AOSIS,so they have a  10 voice in international politics and can make the richer developed world listen to their problems.[A] severely      [B] damage     [C] island[D] critical     [E] grow       [F] mainland[G] louder       [H] predicting    [I] rise[J] completely     [K] geometry     [L] actual[M] extending     [N] 1eading     [O] develop
