Questions about the field modified, created, updated

Hello, here i am with a new question, someone could explain me how
this fields works?
This is how i understand they might work:
1) created, ok this is simple.
2) modified, when this field are updated? I have supposed that it
change every time I update the record. For example when i call save()
on a model with some field changed.
3) updated, why this field are there if I already had modified.

thanks for enlightment!
