Please stop beating on the OP. I think he got the idea. He has been around here for almost two years. I am sure he will be prudent. His question may be a bit elementary to most of us. There was no indication that he is dumb. Give him some credit that at least he came here to ask. All of you provided him some good answers, I am sure he will follow them accordingly.
Respect goes a long way. We all have to start at the bottom.
