Understanding Search Engines What Is The Web? Web Search Lesson Plan Module A1

What is the Internet? The internet is a global network of computers. It is millions of computers around the world, all connected. People often think of the internet as a cloud in space. In reality, every computer in the "inter-network", or internet, is connected by actual wires -- ethernet cables, phone lines, and fiber optic wiring on the ocean floor!

What is the Web? People often use the words "the internet" and "the web" interchangeably. Is there a difference? The World Wide Web is just one part of the internet. The internet also includes e-mail, instant messaging, multiplayer gaming, and FTP (peer-to-peer file sharing). Google Confidential and Proprietary

Deep Web vs. Visible Web When you use a search engine, you only have access to the visible web -- the part of the web your search engine has indexed. The entire web is much larger than any one search engine's index. It is estimated that the deep web is over 500 times the size of the visible web! The deep web includes webpages that are not linked to by other pages, password- protected sites, and private databases (such as library catalogs). Google Confidential and Proprietary

What is a Search Engine? A search engine is a program to help you find webpages on the internet. Search engines do not search the whole web, but only an index of the web. Some examples of search engines include Google, Bing, Yahoo, and Ask. Google Confidential and Proprietary
