What is the difference between Organic and Paid Search results?

Whenever i ask most people this question i just get a big "what?". There seems to be a misconceived notion that the top results on Google are the most relevant (In most cases it goes to the person with the best quality score/budget but we are not here to get into PPC optimization). Generally, the top two links presented are actually paid advertisements and not organic search results.

The organic search results are a bit below the "Sponsored Links" (a nice way of saying paid advertising!). 

A short explanation of what Search Engine Optimization is: The art of letting search engines (Like Google/Bing) know that your website exists and that it is relevant for certain keywords (which relate to the content your site provides). This is a very basic explanation by the way.

I promised this post to a friend of mine so i hope it is satisfactory.
