I would like to order some internet today.
What kind would you like?
What kind of internet is there?
You can get DEL or dial-up.
Which of those two is best?
I would recommend DEL.
So that one better?
It's better because it doesn't tie up the phone.
What do you mean by that?
DEL isn't connected through your phone line, but dial-up is.
So then I can't use my phone if I'm on the internet?
That's correct. With DEL you can do both.
