The Internet
Do you really know what
is out there?
Ok, some vocab
• Internet - A global network connecting millions
of computers.
• World Wide Web - A system of Internet servers
that support specially formatted documents.
• Website - A site (location) on the World Wide
Web.
• Webpage - A document on the World Wide
Web. Every Web page is identified by a unique
URL (Uniform Resource Locator).
Let’s Think
• Is the Internet and the World Wide Web
the same thing?
– Look at the definitions closely
– Not all Internet servers are part of the World
Wide Web.
– World Wide Web is not synonymous with the
Internet. (webopedia)
Another thought
• What is the difference between a website
and a webpage?
– It is simple…webpages make up a website
Using the
Internet
• How do you find information
on the Internet?
“Google It”
(searching
with
Google.com)
– just “google it”, right?
Well, it’s not really that simple. You can
“google it”, but you will find way too much
information.
Lets explore some more information about
search engines…..
Search Engines
• What is a search engine?
– A search engine is a type of software that
creates indexes of databases or Internet
sites based on the titles of files, keywords, or
the full text of files. (learnthenet)
– So, we use a search engine to find other
webpages…that makes sense.
Only Google?
• What are some examples of search
engines?
– Google
– Yahoo
– Altavista
– Dogpile
– The list goes on and on
Which one?
• Which search engine do I use?
– That is up to you and your topic.
• One might not be better than another, but
there are some tips that you need to
know about search engines.
– You know you love tips and tricks! So
continue on….
Why are there so
many pages?
• How do I narrow my search?
– Boolean operators
• The Boolean operators AND, OR, NOT (or AND
NOT), and NEAR tell search engines which
keywords you want your results to include or
exclude, and whether you require that your
keywords appear close to each other.
– Use a Web directory
• a search service that arranges the web pages it
knows about into categories and subcategories.
How did all that
stuff get there?
• How does information get on the
Internet?
– It is a process of publishing the information
on the Internet – anyone can do it – if you
have the knowledge (and sometimes $$$)
– Webpages, Wikis, Blogs, and more
Believe it or not?
• If anyone can put information on the
Internet, should we believe everything
we read?
– No, no, no….do not believe everything you
read
– It could be incorrect or just outdated
• How do I know what is correct?
– I am going to tell you…..
Believe it if…..
• Ask yourself these questions:
1. Who wrote the pages and is the author an expert?
2. What does the author say is the purpose of the
site?
3. When was the site created and last updated?
4. Where does the information come from?
5. Why is the information useful for my purpose?
WOW
I thought I knew about the Internet….
but I was wrong
I think I can do more than
just “google it” now
