Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...
 
First question. Wiki: http://en.wikipedia.org/wiki/Surrogate_key[^]
 
Second question. Google: difference between primary key,unique key and surrogate key[^]
 
In future, please try to do at least basic research yourself, and not waste your time or ours.
