Hi Sathiz, pretty much with adsense what you want to do is setup a website or a blog with wordpress and then put your adsense ads into it. Then the next step is to drive traffic to that site with...
-article marketing
-videos
-forum marketing etc.

once you have implemented these two strategies anytime a visitor goes to your site and clicks on the ads then you get some pennies on the dollar. It adds up after a while depending on how many people you funnel to your site. cheers!
