Google pagerank in simple words

Every one keeps speaking of PageRank. So i thought i would just give my readers a simple basics on it. Here we go. It is a patented method to assign a numerical weightage to each page of a hyperlinked set of web pages, is called popularly as a PageRank.
The founders you might be interested to know are Larry Page and Sergey Brin at Stanford University. It is the heart of Google's software / search algorithm.
It is the combination of PageRank with sophisticated text-matching techniques, that is considered by Google, to find pages that are both important and relevant to the searches made.
Google, does not simply look at, the number of times a key term appears on a page, but examines all the aspects of the page's content, and the content of the web pages linking to it, to determine,the best possible relevant match for your search query. Again Google considers a link from page A to page B as a vote, by page A, favor of page B.
It goes a bit further by analyzing the page that casts the vote. If the Votes are by pages that are themselves already "important", then in the eyes of Google it weighs more heavily and this helps to make other pages "important".
Important, high-quality sites receive a higher PageRank, (the highest being pr10) which Google tends to remember each time someone queries a search term. You may be interested in how Googfle slammed Paid Link sellers.
