How Google Or Search engine Works??

Have you ever think or imagine how google works??

Google Is become part of our life.It is impossible to get a relevant information when we search our query in web, without google.When we need some information we entered key phrases which is called as a KEYWORD in Google,and Google provide most relevant result on the top. BUT HOW IS IT WORK???

Larry Page and Sergey Brin, Two students in Stanford University's Ph.D. program,Started project and goal of that project was to make an search engine which gave each and every relevant information for every search request.
Google's name is a variation of the word "googol," which is a mathematical term for a one followed by 100 zeros. Page and Brin felt the name helped illustrate Google's monumental mission: Organizing billions of bytes of data found on the Web.[source:How stuff]

           Google uses a special algorithm for search queries.Lets see how its works.
Google created automated program called crawler or spiders.Google uses a algorithm called Pagerank. Google sorts the page by its content.when we type any keyword on google.spider start fetching a webpages and webpage fetching a links.Thousands of webpages are stored in billions of machine.There are more than hundreds of  pages and thousands of possible result..
Then how google find relevant result???

               Spiders find how many times that keyword appear in the pages ex.in URL,Title,Description ,Body.How many quality links are there.How many people are talking about that link .that's call Pagerank. Higher Pagerank is topmost result.

 Google offers many interesting feature in next section we will  see some of them.
