A:Do you know much about computers?
B:Not a great deal.
A:I've just been reading an article about them. They'll be used for all sorts of things now.
B:For accounting system and things like that, you mean?
A:Yes, but they are used for other things, too. Do you remember when we went to buy a ticket for the flight to Paris.
B:Yes?
A:The man asked where we want to go, then he type out the information on the form and waited for a reply. A few moment later, he gave us two tickets.
B:Of course, his machine must have been connected to a computer.
A:That's right.
