WHAT IS THE INTERNET?
The Internet, sometimes called simply “the Net,”
is a worldwide system of computer networks—a
network of networks in which users at any one
computer can, if they have permission, get
information from any other computer (and
sometime talk directly to users at other computers).
2
E-MAIL
Electronic Mail (e-mail) is the most widely used
application on the Net. Electronic mail,
commonly called email or e-mail, is a method of
exchanging digital messages from an author to
one or more recipients.
3
CHAT
Another popular feature of the Internet is you can
carry on live “conversations” with other computer
users, using Chat.
Chat is real-time communication between two
users via computer. Once a chat has been initiated,
either user can enter text by typing on the keyboard
and the entered text will appear on the other user's
monitor. Most networks and online services offer a
chat feature.

5
WORLD WIDE WEB
The most widely used part of the Internet is the
World Wide Web (often abbreviated “WWW” or
called “the Web”. The World Wide Web is a
system of interlinked hypertext documents
accessed via the Internet.
6
HYPERTEXT
Hypertext is a method of instant cross-
referencing. In most Web sites, certain words or
phrases appear in text of a different color than
the rest; often this text is also underlined. When
you select one of these words or phrases, you will
be transferred to a page that is relevant to this
word or phrase. Sometimes there are buttons,
images or portions of images that are “clickable”.
7
ACCESSING THE INTERNET
You can access the Internet at home with a
personal computer or at various community
locations, like the library, schools, etc. Be aware
that if you use a public computer to access the
Internet, there is probably an Internet Use
Policy and you will be responsible for following
those rules and policies.
NOTE: To see the Roanoke Public Library’s
Internet Use Policy go to www.roanoke.lib.in.us
then click Policies tab then Acceptable Use.
8
REQUIRED TO GO ON INTERNET
If you are using your own computer, you will
need to have at least 3 pieces of hardware /
software to access the internet.
9
#1 A MODEM
A modem is the piece of hardware that “calls”
your Internet Service Provider (ISP) and
connects your computer to theirs. A modem can
connect through a phone line or through a cable
connection.
10
#2 INTERNET SERVICE PROVIDER
Your computer cannot connect directly to the
Internet. You need a third party, the ISP, to connect
to the Internet. The ISP you chose will provide you
with the necessary software to connect your
computer to theirs, and then to the Internet. Some
Internet providers are free while others charge a
monthly fee. Differences in ISPs include:
Connection speed
Appearance of online ads
Number of hours included in their plan each month
Number of email accounts provided
Web page space available 11
#3 WEB BROWSER
This is the software that allows you to view
graphics and other components on the Internet.
The most popular are Microsoft Internet Explorer
or Netscape Navigator. The appearance of a
particular Web site may vary slightly depending
on the browser you use.
12
ANTI-VIRUS SOFTWARE
Anti-virus software is a program that runs in
the background of your computer and continually
scans your hard drive for viruses. If a virus is
detected, the program notifies you and
quarantines the infected file so you can safely
delete it from your computer.
You want to make sure you have an antivirus
program installed AND up to date on your
computer! Some viruses can be spread just by
opening a website and there is no way to know
until it has infected your computer!
13
FIREWALLS
Firewalls are programs that add another level
of security and are especially important to have if
you connect through a cable modem or another
connection that is “on” all the time. A firewall
protects your computer from someone on the
outside gaining access. Without a firewall,
someone could potentially access the files on your
computer, or send emails through your email
account.
14
COOKIES
A cookie is information that a website puts on your
hard disk so that it can remember something about
you at a later time. Cookies are required for many
websites to display correctly or accumulate
information you are entering.
If it is a reputable website, it is usually safe to accept
cookies.
15
URL
Every website on the Internet has a unique
address and to access that website, you must
know the address. A website address is called a
URL, or Uniform Resource Locator.
16
ADDRESS OF A WEBSITE
The format of website addresses are almost all
the same. Most start with www, for world wide
web. Then comes the actual address of the site,
followed by a “dot” extension, which identifies
the domain. The address is like a house
number-it identifies a specific person or account.
17
DOMAIN
A domain is a group of hosts (or computers that
have web sites on them) that are of a same or
similar organization. The domain is like a street
address—a lot of people live or have accounts
there. There are 6 common domains set up for
US Internet sites:
1. .com Commercial
2. .net Network
3. .gov Government
4. .edu Educational
5. .org Organization (usually not for profit)
6. .mil Military 18
EXAMPLE
An example of a website address is:
www.uncanmanuals.com
“uncanmanuals” is the address.
.com is the domain extension
NOTE: Since every website address must be
unique, the same name may be used for different
websites but they will each use a different dot
extension.
19
TEN POPULAR WEBSITES
You have probably heard of or will hear of these
websites, even if you never use them.
1. Google (google.com)—a site where you can set
up an e-mail account, read the news, get
directions, and go shopping, but at its core
Google is a search engine.
2. Wikipedia (wikipedia.org)—an online
encyclopedia that is free but it is user-written
and edited.
3. Amazon (amazon.com)—it began as a way to
sell books without costs associated with a
physical bookstore and has become a store for
almost everything
20
MORE OF WEBSITES
4. Facebook (facebook.com)—a social networking
website for keeping in touch with old friends and
making new ones.
5. eBay (ebay.com)—an online auction where
people sell everything, from real (DVDs, cars,
furniture) to more conceptual (one man auctioned
his life).
6. Yahoo (yahoo.com)—a search engine, an e-mail
outlet, and a news source.
7. The Drudge Report (drudgereport.com)—Matt
Drudge combines links to other new sources and
stories he writes himself to bring his readers the
latest news and rumors. It broke the Monica
Lewinsky story in 1998. 21
MORE WEBSITES
8. Blogger (blogger.com)—creates a website for
people to blog. Blog is an abbreviation of “web
log”, a term for an online journal, column, etc.
9. Craigslist (craigslist.org)—low-tech, local
version of eBay. It is like a huge community
bulletin board, allowing a person to find just
about anything.
10. YouTube (youtube.com)—allows users to post
short videos.

FINDING A WEBSITE
There is no “directory” available for internet
addresses (websites) because there are so many

SEARCH ENGINES
On the Internet, a search engine is a coordinated
set of programs that includes:
1. A spider (also called a “crawler” or a “bot”) that goes
to every page or representative pages on every Web
site that wants to be searchable and reads it.
2. A program that creates a huge index (sometimes
called a “catalog”) from the pages that have been
read.
3. A program that receives your search request,
compares it to the entries in the index, and returns
results to you.
38
SEARCH ENGINE APPROACHES
Major search engines such as Google and Yahoo
(which uses Google) index the content of a large
portion of the Web and provide results.
Ask Jeeves provides a general search of the Web
but allows you to enter a search request in natural
language such as “What’s the weather in Seattle
today?”
Special tools and some major Web sites such as
Yahoo let you use a number of search engines at the
same time and compile results for you in a single
list.
39
INDIVIDUAL WEBSITES
Individual Web sites, especially larger corporate
sites, may use a search engine to index and retrieve
the content of just their own site. Some of the major
search engine companies license or sell their search
engines for use on individual sites.
40
HOW TO SEARCH
If you know of a specialized search engine such as
SearchNetworking that matches your subject (for
example, Networking), you’ll save time by using
that search engine.
If there isn’t a specialized search engine, try Google
or perhaps other search engines for their results.
41
SAVING A DOCUMENT
You can save a web page to a flash drive or to a
hard drive. You may do this in order to print it
