- •I How up to date did you feel the course was?
- •I That question really relates to my next one. Is there anything that you would add to or take away from the course?
- •Very bottom. You see that little status
- •Is that right? с Yes.

- •I So you're sitting in front of your computer...Somewhere, how do you set about getting into someone else's system?
- •I How can you avoid being hacked into?
- •I Did you feel terribly excited?
- •I How did they track you down?
- •I Now you're helping companies to avoid people like you.
- •I Do you hackers know each other? Is there a competitive element to all this? Is there a kind of rivalry?
- •I Movies sometimes feature hackers.
- •I a recent survey found that four out of ten uk consumers are reluctant to use credit cards for Internet purchases. How risky is it really?

Interview: Webpage Creator
Interviewer How long has your site been up?
John Just a couple of months. It's brand new.
I What's your site all about?
J It's called The Movie Shrine,
www.themovieshrine.com, and it's just a site with movie reviews, strange things I've noticed about certain films, and lots of links to other movie sites.
I Why dedicate your site to this subject?
J I decided to make a site about movies because I've been a huge movie fan for a long time. Right now, films are my biggest hobby.
I What makes your site special?
J I guess my site is just a little less formal than most of the film sites on the Internet. I've tried to make the layout unique and include material for movie fans of all types. It's for people who like movies of all kinds. There are plenty of sites for fans of particular actors or genres of movies like sci-fi, horror, films noir and so on.
I How did you create your site?
J I created the site pretty easily using Netscape Composer, which is a program contained in Netscape Communicator. The actual address is www.geocities.com/orangecow, but I got a free domain name which redirects it to the site.
I What was the most difficult part?
J Oh, the design. Just working out how the site would look and how the pages would link up. I'd tried to put up a couple of websites before but after constructing the main page, I'd lost interest.
I How did you get your domain name?
J I got a free domain name from www.domainzero.com. The price of a 'free' domain is that all kinds of advertising is sent to your email, but that's a small price to pay.
I Have you registered your site on a search engine?
J No, I haven't gotten around to registering on a search engine yet. I'm told you have to really persevere to get listed. Yahoo! just seems to swallow submissions.
I Have you included links to other sites?
J I include many links to other sites. That may be the best thing about my site, the huge number of links. I'm also in a lot of Yahoo! Clubs and I've linked to them too.
I Has anyone linked to you?
J Since my site hasn't been around for very long at all, I don't think anybody has linked to me yet except for a couple of Yahoo! Ctubs.
I How long do you spend updating your site?
J As often as possible but it's difficult during the week. My studies don't leave me a lot of time and I've got other interests. And I need to watch movies sometimes! Generally one update will take from forty-five minutes to an hour.
I What sort of feedback do you get from visitors?
J I haven't really gotten much feedback so far except from people I know and they like it, or say they do! I'm hoping that after more people discover the site I'll start to get more reactions via email.
I Do you have any tips for others creating a homepage?
J Pick a topic you're really interested in. Get a good domain name. Keep your site updated - nobody likes a static site. I would look at lots of other sites too for good ideas.
I What do you intend to do next with your site?
J I'm going to update the Movie Journal section and I'd like to build in new links.
I What's your favourite site?
J It would...my favourite site would have to be the Internet Movie Database www.imdb.com. That's not a very original answer but that site just has such a wealth of information about every kind of movie that it's probably my favourite.
UNIT 16
Communications Systems
In the short term, computers are certainly going to become more powerful and they'll also get cheaper. Erm, that means they'll become much more commonly available. It's likely they'll be integrated with other devices, erm, and may even become specialised...specialised devices you throw away when they go wrong. Monitors are going to change from cathode ray tube monitors to flat screen panels because they take up less space and use less power. Erm, there's likely to be devices used for security, biometric devices, for scanning your eye or taking your fingerprints. They'll be used instead of passwords. Printing...printers...colour printers, colour laser printers are becoming cheaper so more printing will be done in colour. Erm, you'll print your holiday snaps straight from a laser. The shape and design of computers are likely to change and become much more varied because we can now construct the motherboards in flexible form. Er, on the software side, companies are trying hard to improve voice control so you'll be able to talk to your computer to control it without using a keyboard.
Erm, another development which I expect to become more common in the near future is video. You'll be able to use your computer as a video-recorder and
edit video on your computer. I expect the way that software is sold will change too. Erm, instead of buying individual packages people may rent or hire the components they need - wordprocessor or whatever - and connect to them over the Internet. Service providers will make different components available and you'll be charged a fee for the ones you use.
In the longer term they won't be able to make computers any more powerful using electronics so other methods may come in for the data signals in the computer. Perhaps laser lights or even quantum methods will be used. Computers will probably be integrated more with TV systems and with telephony and become much more communication devices. It's likely much smaller devices will be made...probably built into clothing so that you can walk about wearing a computer which will allow you to communicate wherever you go. At home our fridges, cookers and other devices almost certainly will be computer controlled. In the longer term there may even be devices implanted into our bodies to help people with disabilities. Computers might be implanted into the human brain. We might not call them computers in the future but they'll be everywhere.

Computing Support
David Hello, this is Apricot Computers
Service Division. My name's David, how
can I help you? Jennifer Hello, my name is Jennifer and
we're having a problem with one of our
Apricot computers. D Now can you tell me what model of
computer you have? J Yeh, it's an Apricot LS 550. D An Apricot LS 550. OK, is the computer
still under warranty? J Yes, we only got it a month ago. So it
should still be covered. D Can you give me the service tag
number?
J Yes, let me look. It's AM 964...70, D That's AM96470. Wait a moment and I'll just look it up in my database...Is that University of Edinburgh, 21 Hill Place? J Yes, that's us.
D So can you describe what the problem is?
J Well, it doesn't seem to be playing MIDI sound files from the Internet.
D Erm, MIDI sound files. Does it play
other types of sound files? J Yeh.
D And is it only when you're in the
browser on the Internet that you're
having this problem? J No, we're getting the same fault when
we use other programs Uke...erm...
Microsoft En carta. D Right. What operating system are you
using? J Microsoft Windows. D Which version of Windows? J It's Windows 2000. D And what type of processor do you
have in the computer? J It's got a Pentium 3. D And how much RAM is installed? J Let's see...l28 Megabytes. D Is the computer connected to any kind
of network? J Yes, we have a LAN. D What type of network? J It's a Windows NT network. О OK. Right. It sounds as if you may have
a driver fault. Do you still have the
original driver disk you got with the
machine?
J Yes, we've only had it a month so it's all there.
D Well, you could try to reinstall the sound drivers and see if that cures the problem. If that doesn't cure the problem, can you contact us again and we'll send you out some new drivers to try.
J OK, I'll give that a try and get back to
you if we have a problem. D Er, if you're going to contact us again
with this problem, can you quote
this job number. It's E83095. J Er, just a moment. I need to get a pen.
Can you repeat that? D OK, E...83095. J E83095. D That's correct. J Can I take down your name? D Yes, my name's David, David Lister. J OK, thank you David and...er...we'll be
