__**Search Engines**__
__ **Definition-** __ Search engines are websites which store information about webpages and which allow you to search through this information to find the specific page that you are looking for. Some of the most popular search engines are Yahoo, Alta Vista and Google

**__History__** ** The very first tool used for searching on the interbet was Archie. The name stands for "archive" without the "v". It was created in 1990 by Alan Bantage, ** Bill Heelan and J. Peter Deutsch, computer science students at McGill University in Montreal. The program downloaded the directory listings of all the files located on public anonymous FTP sites, creating a searchable database of file names; however, Archie did not index the contents of these sites since the amount of data was so limited it could be readily searched manually. In June 1993, Matthew Gray produced what was probably the first web robot and used it to generate an index called 'Wandex'. The purpose of the Wanderer was to measure the size of the World Wide Web, which it did until late 1995. The web's second search engine Alliweb appeared in November 1993 **. ** Around 2000, Google's search engine rose to prominence.The company achieved better results for many searches with an innovation called PageRank. Microsoft's rebranded search engine, Bing, was launched on June 1, 2009. On July 29, 2009, Yahoo! and Microsoft finalized a deal in which Yahoo! search would be powered by Microsoft Bing technology.
