Lesson 2
The Internet
The Internet
 The largest and most
widely accessed
network is the Internet, a
worldwide network of
computers that is not
controlled by any one
organization. It allows
users to communicate
and access information
in a matter of seconds.
Searching the Web
 The World Wide Web
is used to search and
access information on
the Internet and
requires a Web Browser
application, such as
Microsoft Internet
Explorer to view the
Web site pages.
 A search engine is
used to locate
information on the Web.
A search engine usually
works by sending out an
agent, such as a spider .
They search a database
of Web pages for specific
words or phrases and
then list the hyperlinks
to the pages containing
the text.
Searching the Web
 The words or phrases used in a
search are called the search
criteria . Search criteria
should be carefully specified by
using keywords related to
the topic of interest. Ways to
specify search criteria are:
1.
Surrounding phrases with
quotation marks finds Web
pages that contain the entire
phrase exactly.
plus sign (+)
2. The
can be used to find pages that
contain specified words.
Separating the words with a
space has the same
effect.
3.
4.
The minus sign (-)
can be used to exclude
unwanted Web pages.
The logical operators
AND, OR, and NOT can also
be used. The operator AND
has the same effect as the +
and space. The operator OR
is used to find Web pages that
contain one word or another
or both. The operator NOT
has the same effect as - .
When operators are used in
search criteria, a Boolean
expression is formed, which
evaluates to either true or
false.
Citing Web Sources
 If information from a Web site is to be referenced or
quoted in a report, essay, or other document, a
citation must be used to give credit to the
original author and allow the reader to locate the cited
information. All sources of information used to
support research must be cited. This includes:
Email messages, graphics, sounds, video clips,
and news-groups postings
Citations for Online Sources

Modern Language Association often referred to as
MLA Style . General citation for material
