Introduction
The most popular search engine Technology
Introduction -Nowadays Google is currently the most popular search engine. -We can say Google has a priority on the Internet.
3
Moving on …
Information and webs on Internet - Google search - G-mail - Google map - Google video - So no…
And Google has new technology or software to helpful people for examples .. -Google search engine: -this engine has more functions to find information such as files, images, video. -G-mail -Free electronic mail. -Google map -Mapping service. -Google video -Video service about stores, publications, and videos.

Founders of Gooooooogle
Larry Page (American) Surgey Brin (Russian) In 1995 At Stanford University
•You want to know •Who are the founders of the Intelligent search engine ? •About Founder of Google. •When Surgey Brin first met Larry Page in the summer of 1995. -Surgey Brin was a second year grad student in the computer science department at Stanford university. -When Page showed up at Stanford a few month later , he began searching for a topic for his doctoral thesis. -It was an important decision for him. -Page wanted to know when you look at a Web page.

Search Engine
The search results 3 1
The web server sends a query to the index servers
2 The query travels to the doc servers
Steps of search engine. 1. The web server sends a query to the index servers. The contents of the index servers is similar to the index in the back of a book – it tells you which pages contain the words that match the query. 2. The query travels to the doc servers, which actually retrieves the stored documents. Snippets are generated to describe each search result. 3. The search results are returned to the user in a fraction of a second. --• • • • Nowadays Google is currently the most popular search engine It is more popular than yahoo ,MSN etc. Why ? Because Google are spend less time searching for information and it carries out the search quickly and correctly.

This picture shows the first server office their in of dormitory at Stanford. Sergey Brin had a background in mathematics. He was a genius. He worked in part of the mathematics on these projects for his doctoral thesis.
-If you look at this picture what you can see. -Page was thinking when you look at a Web page, you had no idea what pages were linking back to it. -Because on the internet there are many web sites which are increasing. Now there are over four million. -He thought it would be very useful to know who was linked to whom and he called this the “BackRub project” -It means If you look only forward you newer know who is your BackRub. -Citations are very important when you have that there is even a branch of science devoted to their study. -To continue, Page began building out his crawler. -Crawler is a program for a surfer and keeps information on the webpages. •When he had every web page information on the Internet page, Brin’s breakthrough was to create an algorithm called “Page Rank” •Page Rank is a numeric value that represents how important a page is on the web. •Page Rank is Google is way of deciding a page’s important

Conclusion
The Future Questions/Answers
Source and reference + Technology of Google (http://www.google.com/technology/) PageRank description by original. + How do PageRank work ? (http://www.webworkshop.net/pagerank.html) detail include with formula. + WIRED journal ,August, 2005 (John Battelle, The Birth of Google, WIRED, August 2005) + History of Google (http://www.google.com/corporate/history.html)
I think in the future Google will have an important role because it enables more services on the web for very one in the world. I hope this presentation has given you some useful information. Now If you anyone has any questions , I will be pleased to answer them.
