I need to get internet.
Which kind of internet connection do you want to get?
What kind can I get?
There is dial-up or DEL.
Which one do you feel is best?
I would get DEL if I were you.
DEL is better than dial-up?
It's the best choice ; plus, it won't tie up your phone line.
I'm not sure what that means.
Dial-up is connected through your phone, unlike DEL.
That'll make it impossible for me to use.
Exactly. With DEL you don't have that problem.
