circuit biasing

Can someone explain to me the concept of biasing? I dont have a clue. I must of missed class that day. I have searched many web links and the discussion on biasing is always implied but never actuallly defined.

Questions

1) How to apply biasing in a circuit
2) Why/When do we need to consider using biasing
