History Of Google:-
Google began in January 1996 as a research project by Larry Page and Sergey Brin, a Ph.D. student at Stanford and the company was first incorporated as a privately held company on September 4, 1998.
His supervisor Terry Winograd encouraged him to pick this idea and Page focused on the problem of finding out which web pages link to a given page, considering the number and nature of such backlinks to be valuable information about that page.
In his research project, nicknamed "BackRub", he was soon joined by Sergey Brin, a fellow Stanford Ph.D. student and close friend, whom he had first met in the summer of 1995 in a group of potential new students which Brin had volunteered to show around the campus.
Page's web crawler began exploring the web in March 1996, setting out from Page's own Stanford home page as its only starting point. To convert the backlink data that it gathered into a measure of importance for a given web page, Brin and Page developed the PageRank algorithm.
Analyzing BackRub's output—which, for a given URL, consisted of a list of backlinks ranked by importance—it occurred to them that a search engine based on PageRank would produce better results than existing techniques (existing search engines at the time essentially ranked results according to how many times the search term appeared on a page). A small search engine called RankDex was already exploring a similar strategy.
Convinced that the pages with the most links to them from other highly relevant Web pages must be the most relevant pages associated with the search, Page and Brin tested their thesis as part of their studies, and laid the foundation for their search engine. Originally, the search engine used the Stanford University website with the domain google.stanford.edu. The domain google.com was registered on 15 September 1997, and the company was incorporated as Google Inc. on 4 September 1998 at a friend's garage in Menlo Park, California. The total initial investment raised for the new company amounted to almost US$1.1 million, including a US$100,000 check by Andy Bechtolsheim, one of the founders of Sun Microsystems.
In March 1999, the company moved into offices in Palo Alto, home to several other noted Silicon Valley technology startups. After quickly outgrowing two other sites, the company leased a complex of buildings in Mountain View at 1600 Amphitheatre Parkway from Silicon Graphics (SGI) in 2003. The company has remained at this location ever since, and the complex has since come to be known as the Googleplex (a play on the word googolplex). In 2006, Google bought the property from SGI for US$319 million.
The name "Google" originated from a misspelling of "googol" . which refers to the number represented by a 1 followed by one-hundred zeros. Having found its way increasingly into everyday language, the verb, "google," was added to the Merriam Webster Collegiate Dictionary and the Oxford English Dictionary in 2006, meaning, "to use the Google search engine to obtain information on the Internet.
Google PageRank Formula
The principle behind PageRank calculation is that every link is a vote. The more links to a page, the better it must be - and the higher PageRank it is assigned. But - unlike a democratic society - all votes are not equal: Pages with a high PageRank have a bigger vote.
Google's formula looks like this:
PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn)) .
where,
D= Dumping Factor
for a moment forget about D (Dumping Factor), then the formula Look likes.
PR(A) = PR(T1)/C(T1) + ... + PR(Tn)/C(Tn) .
So what this formula says is: In order to find the PageRank for a page, called A, we must find all the pages that link to page A. Let's say we find a page, T1, which has a PageRank of 20 and links to 5 pages, then page T1 will give 4 points (i.e. 20/5) to page A. We do this for T2, T3 and all other pages linking to page A - and add up the values.
The only snag is that page A might link back to some of these pages - or link to some pages that in turn link to these pages, and if page A's PageRank increase, so will theirs. Therefore these calculations will have to be done again and again i.e. iteratively. This is where the spreadsheet on this site comes in handy.
PageRank could also be thought of as a probability. If your page has a PageRank of 20, and there are 4.285.199.774 pages indexed by Google, it follows that the odds that a "random surfer" is reading your page right now are 20/4.285.199.774.
