Were gonna take a closer look tonight again at the future of the Internet. Not that we have anything but the vaguest id

17、ea where its going in the long run. One of the truly fascinating and somewhat unsettling aspects of the Internet revolution is how many technologists and scientists say that the future may hold any number of surprises. So were going to inch our way into the future.P. At the Internet World Trade Show

Imagine work, society, economics, relationships, all transformed, when anyone, anytime can get any message or knowledge or amusement they want, anywhere on the planet withou

19、t so much as a wire.S2. In many ways, the Internet is the worlds largest experimenting anarchy, because all of a sudden, the citizens of the world are in charge, and no single government or governing body is in charge of what they do.P. Keep in mind that the web, transmitting by satellites, cell pho

20、ne, cable, goes through no one central location that anyone controls. So many of the boundaries that exist today, political and economic, will be strained as never before.

27、tes come in third.I: Are there people who are spending too much time online?G: Based on my research, about 6 percent of people online are using the Internet compulsively.

But people feel closer, more quickly to the people they communicate with online than in real life; time passes freely,

31、 and people like the anonymity. With every other communication medium- newspapers, magazines, TV shows -there is a beginning and an end. But online, there is always another link, another banner, another person to answer that question.I: So how do people know when theyve gone too far?G: There are two

32、 things to ask. Are they using the Internet to alter their mood on a regular basis? And, is it interfering with their life in any way?I.

Have a specific task you are going to do and write

34、that down. Put a clock next to the screen so you can keep track of time. If you find yourself getting over-stimulated by some site, limit your access to it. Ask someone to monitor your use or put the computer in the family room or the living room, where other people can see you. Try to beef up your

35、realtime relationships to compete with your cyberfriendships. If youre shopping too much, go to a store instead. If you cant control your use, you might have to just log off.Part III Digital McLuhanSummary:Marshall McLuhan, a communications expert from Canada, never touched a personal computer. But

36、his research on the media and their effect on people and society remains relevant today. He was the first thinker to really look at television as something that had a serious impact upon our society. Although he was writing about television, an enormous amount of what he said has even more applicabi

37、lity to the Internet age. He said that television was turning the world into a global village. And the notion of village becomes much more meaningful and real in our digital age. He saw a time when everyone would be a publisher with the help of the Xerox machine, and now the web is even expanding an

38、d amplifying that.Tapescript.I Interviewer L - Paul LevinsonMarshall McLuhan, a communications expert from Canada, never touched a personal computer. He died in 1979. But his research on the media and their effect on people and society remains relevant today. Paul Levinson, an American high-tech exp

39、ert knew Professor McLuhan, and discusses his impact in a volume entitled Digital McLuhan: A Guide to the Information Millennium.I. Mr. Levinson, why is Marshall McLuhan such an important figure?L. Well, he did his writing in the 1950s,1960s and 1970s. And those decades, of course, were the first ye

40、ars of television. And he was the first thinker to really look at television as something that had a serious impact upon our society. Interestingly, although he was writing about television, an enormous amount of what he said has even more applicability to the Internet age. For example, he said that

41、 television was turning the world into a global village. What he meant by that is when everyone watches the same thing on the television screen, that group thats watching that television program is a community of sorts. Its like the people in a village all hearing and seeing the same thing. In contr

42、ast, now in the 1990s, as we move into the new millennium, when people communicate on the web, and through the Internet, they are not only doing and hearing and seeing the same thing, they are also participating, communicating among each other. And so, the notion of village becomes much more meaning

43、ful and real in our digital age.I. TV was a. or is a one-way medium, whereas the Internet is a . is two-way.L. Thats right. There is a crucial difference right there. Most media in the 20th century, in fact all the major media of the 20th century radio, motion pictures, television -were and are like

44、 newspapers and books, one-way media. The telephone, which of course was invented in 1876, is a two-way medium. But, its a two-way personal medium. There is nothing public, or there shouldnt be much public about a telephone conversation. What makes the Internet so different is that it is public but

45、it is also interactive and two-way.I. Marshall McLuhan saw a time when everyone would be a publisher. He was referring to the Xerox machine, the copying machine. Today, we have the Internet which makes everybody an editor, and . or makes everybody a publisher but not an editor. Isnt this a problem w

46、hen everybody is a publisher but there is no editor around?L. The traditional value of the editor is to, in some way, stipulate and vouch for the quality of the publication of the production. So yes, there is a concern that when anyone can put anything on a web page, you know, there is no safeguard

47、for the quality. But, on the other hand, and there is always another hand, I think the reason why McLuhan celebrated first the Xerox, allowing every author to be a publisher, and why Im now so pleased that the web is even expanding and amplifying that, is . there is also the danger of editors keepin

48、g out of the mix things that are good. What the web does is it removes the middle man and allows the creator to communicate directly with his or her audience and on balance I think thats a good thing. There will be more drivel available. But, therell also be more gems that would otherwise be hidden

49、from public view.Part IV Beware hackers!1. 75%2. Juveniles, usually in their late teens to early twenties3. They do it as a challenge.4. A former hacker, now a security consultant5. To fight the holes in the firewall - the protection device between different security systems6. Because they can bring

50、 expertise that only hackers understand, a holistic perception of computer systems7. Because they are so in-depth within a system.8. 90% or 95% effectiveness is better than not having anything at all.9. A good security policy will protect you from an employment level up to a system administration le

51、vel.Tapescript:H - Holmes T - Teresa B - BevanH: Lets talk about how widespread the problem is. Many people think the number of companies or government agencies whose security is breached is small. Is that the case or not?T: No, I think anybody who has information online . its gonna be a huge concer

52、n for anybody. Mostly because if youve got information on these websites, anybody can actually get into them. The thing that you need to know is how to be careful. Its kind of like think of it as a security system in a building, lets say. If you have a security guard in the front, youre protected in

53、 that area. You need to do that all around the entire circle, lets say, to make sure that your entire information on these websites is completely protected.H: I . I read a statistic that said that something like 75 percent of companies online have been hacked, whether they know it or not. Is. is tha

54、t . Thats huge.T: That is huge. And, in fact, it can be minor to major. Most of them are usually on the minor scale - that being, some information getting in. And at this point in time, a lot of experts are saying that the hackers that are going into these sites are juveniles, usually in their late

55、teens to early twenties. And most times, theyre really just doing things as a challenge, as a way to get in, because its something that they can do.H: Now, Mathew Bevan, whos a . whos a former hacker, who became a security consultant. Now . now, tell us about that. This happens a lot?T: This . right

56、 now, this is happening a lot. Mostly because these hackers that are young, juvenile children, or teens, as we have said, really know the industry. They know the computer so well, even more so than a lot of the security, you know, computer systems that are already in place. Theyve really become kind

57、 of an asset, or they could be a consultant, as . as Mathew is, because they really know how theyve got into them. And these are the people that a lot of corporations can actually use, because what theyre doing is theyre fighting the holes in the firewalls which are the protection device between the

58、 different security systems -and theyre really kinda getting into the loopholes or the niches there. By doing that this is great information that companies can use, because they may know, Okay, that . part of that . our website is not, you know, protected.H. You were a hacker. And how important is that for you in your current job, which is as a consultant for companies who fear hackers?B. Well, in my current job, what I can do is bring expertise that perhaps only hackers will actually understand. Its kind of a perception of computer systems, sort of a holist
