so if i understand those <meta http and meta name= will be worlds wich will be found on google or what?
Yes, or that was the original purpose. Keywords are pretty much outdated. The use of meta keywords stems from the time when search engines could only index a limited number on words on each page. That hasn't been the case for a long time. SEs have no reason to use keywords anymore, especially since thay've been used for spamming, and basically they don't.

but why meta name="author"?
To tell people who the autor of the page is. You don't need to use any of the Meta stuff if you don't want to.

In this case it's used to link a style sheet to the page.
