Introduction
Websites are a dime a dozen these days.
Verify the authenticity of a website
before you purchase a product or
research distance-learning education for
your next degree.
Introduction
When you're performing daily tasks online and browsing
various websites, you may not always think to investigate
as to whether the website is legitimate. As long as you're
just reading content, it may not be a huge issue, but before
you make a purchase with a website that you're not
familiar with, it's best to do a quick check. You can verify
that a website is legitimate by checking the InterNIC
network information website.
Key Terms Defined
InterNIC - InterNIC is the "Network
Information Center" of the Internet. It
maintains records on online websites and
allows individuals to file complaints against
website registrars (the companies that provide
services to website owners).
Database - Databases are usually collections of
journal and magazine articles, dissertations,
reviews, and abstracts. A database consists of
individual records.
Key Terms Defined
Internet - The Internet lets you transfer
information around the world in seconds. It is a global
collection of networks, both big and small. These networks
connect together in many different ways to form the single
entity that we know as the Internet. One of the greatest
things about the Internet is that nobody really owns it.
Registrar - is an ICANN or Internet Corporation for
Assigned Names and Numbers accredited company who
has the authority to register domain names. Registrars are
competitive retailers of domain names like .info, .coop,
.mobi, .name, .pro, .museums, and others.
Key Terms Defined
URL - Abbreviation of Uniform Resource Locator
(URL) it is the global address of documents
and other resources on the World Wide Web.
The first part of the URL is called a protocol
identifier and it indicates what protocol to use,
and the second part is called a resource name
and it specifies the IP address or the domain
name where the resource is located. Examples:
ftp://www.pcwebopedia.com/stuff.exe and
http://www.pcwebopedia.com/index.html
Key Terms Defined
Legitimate - according to law; lawful: the
property's legitimate owner, in accordance
with established rules, principles, or standards
and in accordance with the laws of reasoning.
How to Tell If a Website is Legitimate
Look for consistency in design. Your first line
of defense is a critique of the flow and
"readability" of the website. Ask yourself if
images and text are arranged in a way that is
easy to follow. Legitimate websites most often
do not look as if they have been hastily thrown
together. A website worth its weight will
employ established rules of design with text,
images and navigation.
How to Tell If a Website is Legitimate
Research websites that claim to be businesses
before you perform transactions or provide
information. The Better Business Bureau is a
good place to start.
Be absolutely sure a website is trustworthy before
you enter any private information, including
passwords. Hypertext transfer protocol secure
(HTTPS) indicates a type of network security
protocol. The "s" in "https" literally stands for
"secure."
Boolean Searches
Boolean searches - allow you to combine words
and phrases using the words AND, OR, NOT and
NEAR (otherwise known as Boolean operators) to
limit, widen, or define your search. Most Internet
search engines and Web directories default to these
Boolean search parameters anyway, but a good
Web searcher should know how to use basic
Boolean operators.
Boolean Searches
How to do Boolean Searches
You have two choices: you can use the standard
Boolean operators (AND, OR, NOT, or NEAR, or
you can use their math equivalents. It depends on
you, the searcher, on which method you're more
comfortable with.
Boolean Searches
Boolean Search Operators
•The Boolean search operator AND is equal to
the "+" symbol.
•The Boolean search operator NOT is equal to the "-“
symbol.
•The Boolean search operator OR is the default setting
of any search engine; meaning, all search engines will
return all the words you type in, automatically.
•The Boolean search operator NEAR is equal to putting
a search query in quotes, i.e., “Sponge Bob Squarepants".
You're essentially telling the search engine that you want
all of these words, in this specific order, or this specific
phrase.
Boolean Searches
More Examples
• Using AND narows a search by combining terms; it will
retrieve documents that use both the search terms you specify, as
in this example:
Portland AND Oregon
Using OR broadens a search to include results that contain either
of the words you type in. Example: Liberal OR Democrat
Using NOT will narrow a search by excluding certain search
terms. Example: Oregon NOT travel
Using Boolean Advance Search
