Search Engines are applications on the Internet that have massive databases that store millions of web pages. People use search engines to find information they are looking for by typing in search terms related to the information.
A search engine works by using small programs (spiders or bots) to fetch as many documents as possible. Another program, called an indexer, then reads these documents and creates an index based on the words contained in each document. Search engines then use an algorithm to determine which web pages they display in the results from the search. The algorithms calculate a ranking number and assigns it to a page based on the search terms.
