====== Google Searches vs. Wikipedia ======
|Google searches the entire internet.  Note the kind of suggestions made in the drop-down box under the Google input box.\\ [[http://www.google.com/search?q=hvac&sourceid=navclient-ff&ie=UTF-8&rlz=1B3GGGL_enUS300US300|Google search for HVAC]].\\ [[http://www.google.com/search?q=refrigeration|Google search for refrigeration]]|

|Searching for HVAC brings up 17,400,000 web pages plus lots of advertising.  The information you want is probably out there somewhere, but it takes a while to browse that many pages.|

|Wikipedia is just one website on the internet.  It is designed to give more focused answers than Google.  Every suggestion it makes is to another page in Wikipedia|

|Notice the difference in color in the text on Wikipedia.  Each blue word or phrase is a link to another part of Wikipedia.  This makes it easy to go from [[WP>HVAC]] to [[WP>air-conditioning]].[[WP>refrigeration|Wikipedia article on refrigeration]].|
