Accuracy and Precision

I'm struggling to get my head around the difference between Accuracy[]
and Precision[], and similarly AccuracyGoal[] and PrecisionGoal[].  I'm 
writing a small optimisation package at the moment, and would like my 
options to be similar to those of FindMinimum[], but can't sort out the 

I get the same answer for Accuracy[1] as Precision[1], and 
for Accuracy[1.] as Precision[1.], and for 
	Accuracy[1.000000000000000000000000000000000001] as

I'm afraid the accuracy of my brain is unable to cope.



(Accurate and Precise answers most welcome)
