conjunctions - Why do we use a comma before "and"?








Often times, I find myself writing sentences like the following:




"... to integrate four granularities
of features: first, second, third, and

fourth."




I am just curious to find out if there should be a comma before and. Can someone explain the reason for having (or not having) the comma?
