CSIS 572 Google (www.google.com) Yahoo (www.yahoo.com) Dogpile (www.dogpile.com) Excite (www.excite.com) Ask (www.ask.com) Hotbot (www.hotbot.com) Bing (www.bing.com) *A search engine is a tool designed to search for information on the World Wide Web. *A search engine has 3 parts. The 1st part is a program called a spider; spiders get their name because they crawl over the Web using multiple “legs” to visit many sites simultaneously. As the spider collects data, the 2nd part of the search engine, an indexer program, organizes the data into a large database. When you use a search engine, you interact with the 3rd part: the search engine software. This software searches the indexed data, pulling out relevant information according to your search. The resulting list appears in your Web browser as a list of hits, or sites that match your search.
