[speaker001:] I would like to order some internet today.
[speaker002:] What kind would you like?
[speaker001:] What kind of internet is there?
[speaker002:] You can get DEL or dial-up.
[speaker001:] Which of those two is best?
[speaker002:] I would recommend DEL.
[speaker001:] So that one better?
[speaker002:] It's better because it doesn't tie up the phone.
[speaker001:] What do you mean by that?
[speaker002:] DEL isn't connected through your phone line, but dial-up is.
[speaker001:] So then I can't use my phone if I'm on the internet?
[speaker002:] That's correct. With DEL you can do both.
