How does Google work?

  1. Aug 24, 2005 #1
    The search feature on my computer can take up to a minute and google can search the entire internet in a fraction of a second. How does it do that?

    Even with everything archived, it seems like the processing power needed to run such a search engine would be astronomical.

    Google has a really large linux cluster based on commodity hardware.

    Simple Answer :: Google Owns.

    But if I were to take a guess, I would say that google does not search the entire internet. But narrows down the search via your keywords. Im not exatly sure of that, however.

    Yes, Google uses "spider" bots to "crawl" portions of the Internet to index sites, along with their keywords.

    The Founder's Ph.d. Thesis is out there. it discuses the tech he ended up using in building google. I forget the name of the paper. some one used it as a presentation topic in my seminar class.
