I am writing this summary on google,i donot think any person who have ever used
internet do not know this name.Google is
internet company,firstly google started as a single serch engine at that time Yahoo yas internet giant but exploded on internet like a nuclear Bomb from its
facilities provided on internet.
Websites Like Orkut,Blogspot,Gmail,Adsense,Adword,Analytics,youtube are websites which hold top twenty rank in website ranking system.
In present situation google is leader in network expandation and this company have beated Yahoo from better facilities.
