So What Have I Learned Here?
That they really want you to know your layers inside and out…not just an exact
definition but other similar definitions. Let’s face it…its enough to drive you friggin
nuts. The only advice I can give is to memorize the one’s that are extremely technical,
geeky, and just plain obnoxious. Then write your own definitions to check your
understanding of the layers and have someone else (like a teacher or really
knowledgeable friend) check them over for accuracy.
