Thanks John. I think it would be a good idea to read up on this in my A+ book we used in class. I'm still a little confused, but i think if I re-visit this in my book, I'll better understand it. Not to mention, My goal is to get my A+ certification this summer, so I need to get started.
If I need to ask more questions about install versus repair, would it be best to open a new post later?
As always thank you very much for all your help.
