What's the difference between the pill and the morning-after pill?

I'm 16 and thinking about having sex with my boyfriend for the first time. If I do choose to have sex with him I want to be as safe as possible. Of course we'll use a condom, but as I said I want to be as safe as possible so I was wondering about birth control pills. I've heard of the "morning after pill" and of "the pill." What's the difference? I found this info....
