a chord, a string and a pad

[rol leider]

A question for all the gear people on the list. I've read these terms lots, 
and feel like I know what they mean, but I'm not positive that I really do. 
What is:
1) a chord
2) a string; and
3) a pad?

I'm sure that the question sounds stupid to some, but if you don't ask....
Cheers

Rol
