Search Engines

Today. I saw about search engines.

First, a search engine is a web-based tool that enables users to locate information on the World Wide Web.

There are a lot of it, for example:

• Google. Google Search Engine 

• Bing

• Yahoo  

• AOL

• Ask.com

• Excite

• Baidu

• DuckDuckGo

I thought was easy to search for good and reliable information in the search engine, but it is a very complex system. Google offers us many options and we can modify them to whatever we want.

In google you can finf a lot of content, facts or opinion. Sometimes can be dificult know which is a good and relevant information. For that reason, some personans prefer use lybrari data bases than a search engine, but, unfortunatelly it has a cost. Sometimes, we as students can not offered us that books. so I think that it is a advantages of use search engines.
