Couple of BASIC questions

[LRAO]

1. What do you call each time your dealt a pair of hole cards? I think "hand" refers to a pair you actually play. The reason why I'm asking is b/c I am creating a spreadsheet and on it I am including a column to track how many "hands" are dealt between hands that I play.

2. What are the nine positions called? I have:

Button
SB
BB
UTG
UTG+1
MP1
MP2
MP3
CO

Is this correct?
