File transfers, electronic mail, messaging, news feeds, and the Web are all made possible by the Internet. There are several parts to the Internet. These parts include computers, communication hardware, software, and standards. The Internet was designed to be redundant and fault tolerant. This means that there are many duplications to ensure the communication takes place. The World Wide Web is a collection of programs, called web servers, running on Internet networks all over the world. On these servers are over 50 billion hypertext pages. Each page has its own uniform resource locator (URL) or web address. Searching through all of this information is supported by software called a search engine. Learning to perform good searches is important for a user and for the search engine.
