Ball Spin Rate Off My Driver

Can someone clue me in on the effects of ball spin rate from my driver. Don't quite understand the effects of high spin and lower spin rate. For more distance do I need more or less spin? How about accuracy? To hit straighter driver, do I need more or less? Does spin rate effect trajectory or high or lower launce angle? Any info that you can give me will be much appreciated. Thanks in advance.
