Well, not exactly that. Microsft web site has the highest page ranking in Google. The top 3 sites in google page ranking are:
www.microsoft.com/
www.AltaVista.com/
www.yahoo.com/
CNN in number 7 and Google itself is 8. How do you find that out? Search for this term in google, "http://" Here is a short explanation of Google Page Rank:

The heart of Google is PageRank™, a system for ranking web pages developed by Google founders Larry Page and Sergey Brin at Stanford University. PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B. But, Google looks at more than the sheer volume of votes, or links a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."
Important, high-quality sites receive a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important and relevant to your search. Google goes far beyond the number of times a term appears on a page and examines all aspects of the page's content (and the content of the pages linking to it) to determine if it's a good match for your query.

Obviously page ranking is a number status assigned to a web site by Google in a scale from 1 to 10. If you install the google tool-bar with full options you can check out the page rank of a site immediately.
The formula to count PR:
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
In layman's terms PR(A) is the Pagerank™ boost your page will get after being linked from someone else's site (t1). PR(t1) is the pagerank of the page which links to you and C(t1) is the amount of total links that (t1) has. It is important to know that a pages voting power is only .85 of that pages actual PR and this voting power gets spread out evenly between all sites it links to.
(d = The damping factor = is the amount of your PR which you can actually pass on when you vote / link to another site. The damping factor is widely known to be .85 . This is a little less then the linking pages own PR. )
Imagine quantumcloud.com was linked by XYZ.COM's link page which had a PR of 4 and 9 other links, here's how the formula should look like:
PR(AKA) = (1-.85) + .85*(4/10)
PR(AKA) = .15 + .85*(.4)
PR(AKA) = .15 + .34
PR(AKA) = .49
To sum up my site would get an injection of .49 PR after being linked from a page with a PR of four and 9 other links.
Lets say I was linked from a site with a PR of 8 - double the previous example's amount, which had 15 other links, a total of 16 outbound links, my boost would be:
PR(AKA) = (1-.85) +.85*(8/16)
PR(AKA) = .15 + .85(.5)
PR(AKA) = .15 + .425
PR(AKA) = .575
(Incase, you are interested
[http://www.quantumcloud.com/] has a page rank of 5.
This forum has not been indexed by googlebot yet. Only the forum index page. But it is already the 2nd link on google if you search for bangladesh forum. As of I am writing, this single forum index page is on the 7th reulst page if one searches for Java Forum. Page rank 5 is good. And if we can get a few more thousands links from other web sites, we can get upto page rank 7 or 8! Which will be a great success.)
Page rank varies from page to page even on a single web site. The gateway page or index.htm / index.php gets the highest page rank. Usually. Because most backlinking web sites link to this page.
There is a whole search engine optimizing industry that has evolved around how google thinks.
