What is Google?
Well let me explain here. Most people know google by their web search engine called Google Search. Google is the most-used search engine on the Web.
In a simple explanation, Google is the most popular search engine in the world.
Google receives several hundred million queries each day through its various services. They originally created by Larry Page and Sergey Brin in 1997.
Beyond the original word-search capability, Google Search provides more than 22 special features, such as: synonyms; weather forecasts; time zones; stock quotes; maps; earthquake data; movie showtimes; airports; home listings; sports scores, etc. (see below: Special features). There are special features for numbers: prices; temperatures; money/unit conversions ("10.5 cm in inches"); calculations ( 3*4+sqrt(6)-pi/2 ); package tracking; patents; area codes; plus rudimentary language translation of displayed pages.

A Google search-results page is ordered by a priority rank called a "PageRank" which is kept secret to avoid spammers from forcing their pages to the top. Google Search provides many options for customized search (see below: Search options), such as: exclusion ("-xx"), inclusion ("+xx"), alternatives ("xx OR yy"), and wildcard matching ("xx*").
