variables?

Hello all, I need some reinforcement with variables.
Are instance variables the same as fields( which are found outside a method,
but within a class). And local variables are found within methods. Is that
correct terminology?; the reason I ask is because a couple different books,
and sites refer to these variables by different names. My understanding is
instance variables become the state of a object, whereas local variables
work with the methods. Can anyone verify this. Thanks again
