  people find the information they are looking for
  online using keywords or phrases. It looks for
  the results in its own database, sorts them and
  makes an ordered list of these results using
  unique search algorithms. This list is called a
  search engine results page (SERP).Search engines
  are able to return results quickly.It enables
  users to locate information on the World Wide
  Web. Popular examples of search engines are
  Google, Yahoo!, and MSN Search.
