Do you know much about computers?
Not a great deal.
I've just been reading an article about them. They'll be used for all sorts of things now.
For accounting system and things like that, you mean?
Yes, but they are used for other things, too. Do you remember when we went to buy a ticket for the flight to Paris.
Yes?
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.
Of course, his machine must have been connected to a computer.
