Using the World Wide Web
This module covers aspects of the "World Wide Web" including: search engines, domains, and Internet search strategies. When you have completed this section you should be able to:
understand the organization of the Internet.
The Internet is not one entity. It's a network of networks that connects tens of millions of computers worldwide. When you connect to the Internet, you usually do so through a local Internet service provider (ISP). That ISP has dedicated lines connecting to a Point of Presence (POP), which is where other local users join the network. These POPs all form a network that then connects to other networks, which are, in turn, connected to even more networks. None of these networks controls the whole thing. Instead, they operate according to rules and standards set by organizations like the Internet Society.
identify the major types of websites.
E Commerce Websites - Onlines stores allowing you to shop from home.
Blogs - Allows direct contact with readers, usually for personal information.
Personal Websites - Used for friends and family to share information.
Photo Sharing Websites - Upload and share photos online.
Social Media and Networking Websites - Examples are Facebook and Linked In. Allow socializing for individuals and groups.
distinguish between: the public Web that search engines find, and the" DEEP WEB" also known as the "invisible Web", which contains special sources the library purchases for your research neeeds
choose an appropriate search engine; and go with the strengths of the public Web to obtain information on colleges, non-profit organizations, or companies. Know where to find current news, sports scores,or job postings.
In order to feel at home on the Web, know these four concepts:
1. Domain Names
Found at the end of its address, the domain name tells you who sponsors a Web page. Widely used domain names are: com (company), org (organization), edu, (education), gov (government) and net (network).
2. The Internet
The World Wide Web is one part of the Internet, a world-wide computer network.
Each Web page has a Web address called its Uniform Resource Locator (URL). For example, the URL of Miami Dade College is: www.mdc.edu.
4. Groups on the Web
The Web is made up of information published by many different groups.
When you enter your search in a search engine, it searches within its own database of web pages for the keywords you enter, wherever they appear on a web page.
Subject directories are collections of websites that people have selected and organized into broad subject areas. Evaluating Web Sites Since there isn't always a review process for the public Web, you will need to carefully evaluate the quality of the material you find.

To Use or Not to Use
"My instructor says I can't use Web sources for my paper. What can I do?"
Ask your instructor to clarify this, because there are really 'two Webs.' There is the public Web that search engines find, and there's the "invisible Web," which contains special web sources the library buys that only the Miami Dade College community can access and use for research.
Go with the strengths of the public Web:
For very current information such as news, weather, sports and stocks.
To search for job listings, shopping, auctions and travel services.
To obtain information on famous individuals or companies.
To access social networking sites such as Facebook.
There may be better places to look than the public web:
To find articles in scholarly journals.
To find articles in popular magazines and newspapers.
To search databases that index articles in many academic disciplines.
To locate the full text of articles and books that are copyrighted.
The domain name tells you the type of organization sponsoring a page. It is a three-letter code that is part of the URL and preceded by a "dot." Here are the most common domains.
.edu educational institution
Page comes from an educational institution, it does not mean the institution endorses the views published by students or faculty members.
.com commercial entity
Companies advertise, sell products, and publish annual reports and other company information on the Web. Many online newspapers or journals also have .com names.
Federal and state government agencies use the Web to publish legislation, census information, weather data, tax forms and many other documents.
.org non-profit organization
Nonprofit organizations such as charities use the Web to promote their causes. These pages are good sources to use when comparing different sides of an issue.
