13. Internet –Key Terms

14. Closer Look: Domain names Computers use IP addresses, which are
a series of number. However, it is
difficult for humans to remember
strings of numbers. Because of this,
domain names were developed and
used to identify entities on the
Internet rather than using IP
addresses.
 A domain name is the address where
Internet users can access a website.
 The domain name must be registered
before it can be used. Every domain
name is unique. No two websites can
have the same domain name.
Domain names are preceded by "www" (which is not part of
the domain name). All domain names have a domain suffix,
such as .com, .net, or .org. The domain suffix helps identify the
type of website the domain name represents.
The suffix is known as the top-level domain name and it
categorizes the group that is authorizing the website. The top-
level domain name identifies what type of organization or
person is publishing the website. For example:
.com = company
.org = non-profit organization
.edu = educational institution
.biz = business
.net = network
.gov = government
Countries have domains too, for example, .uk = England
.gov sites and .mil sites must pass a test to verify they are real
government and military websites

15. Searching on the Internet
A search engine is a tool for finding information
on the web. It finds and stores information
about the pages on the web and analyzes the
information so it can be searched easily.
Google's search engine is used more than any
other. Another popular search engine is Bing.
Keywords are the words people type into
search engines.
After you do a search for your keywords,
Google displays a list of search results for you.

16. Searching on the Internet (cont.)
Search results are a list of web pages that are most relevant to the keywords you searched.
In a regular web search, your search results will appear as a list of text results that are linked to web
pages (hyperlinks). It is also possible to do searches for other types of results, such as images or
videos.
Organic links are the regular links that appear when you do a search.
Organic links appear because Google has searched through those sites and believes they are the most
likely to provide information on the keywords you searched.
Sponsored links are links that companies paid Google to display when people type those keywords.
Sponsored links may provide relevant information, but they are also likely to try to sell you something.
Google did not judge those sites and decide they were the most appropriate ones for your keywords.
The links that appear in search results usually go to real web pages with content, but sometimes they
do not.A dead link is a link to a web page without any content. Sometimes an error message appears
when you click a dead link. A link could be dead because the page the link was supposed to take you to
has moved to a different web address or because the page is no longer being maintained or updated.

17. Searching on the Internet (cont.)
A Google search usually results in links to many
different web pages.
Using more specific keywords when you are
searching makes it easier to find the information
you want. If you do a search and do not get the
kinds of results you want, you can change your
search keywords to be more specific. This is called
refining a search.

18. Searching on the Internet (cont.)
Since there is no way to make sure that everything on the Internet is true and can be trusted, users
need to think about whether what they read is believable.
The RARA method of website evaluation includes: reliability, accuracy, relevance, and authority.
• Reliability: The website must say where the information came from. You should be able to check to
see that those sources are real. Also, think about why the person put up the site.
• Accuracy: A site is usually accurate if you can find the same information in other locations, and if
the sources cited on the web page actually support the information. Other clues include correct
dates, correct spelling, and the same or similar data in other locations.
• Relevance: Check the dates on the website. They need to be relatively recent. For instance, any
websites that have information that is over five years old are not useful if you are looking for
information on computers. Look at the way the page is written; if the author seems to only be
telling one side of the story, you may want to look elsewhere.
• Authority: It should be apparent who is responsible for the web page. A trustworthy site should be
able to tell you why they are a good source of information.
