Clusters.....why?

Hello,

Being new to Oracle, there are a few things I do not understand. I was hoping someone could help me with these three things since they do not make any sense to me:

1. What does the 'Optimal' parameter do for rollback segments?
2. What is a cluster? Although I have read the Oracle book on clusters, I cannot even begin to build a picture of this in my mind.......
3. When dealing with 'Profiles'....what is meant by a 'composite limit'?

Thank you for your help.
