Can you explain these to me? What are the differences, what do you do, how do you learn? I have always been interested in all this stuff. I would search but am to lasy Thanks

Sad to hear that you are lazy
Unfortunately for you it would have taken less effort to click the search button and type what it is you are looking for, as opposed to starting a thread on topics that are covered, and typing everything that you just said


I'll even take a step for you here is the Search Button
Good luck
