What is the Internet?
The Internet is a vast network that connects many independent networks
spanning over 170 countries in the World. It links computers of many
different types, sizes, and operating systems, and, of course, the many
people of those countries that use the Internet to communicate.
Who Owns the Internet?
No organization, corporation or government owns or runs the Internet.
Instead, many people and organizations voluntarily participate in task
force groups who meet to develop standards for the many various technical
needs of running the Internet.
What can I do on the Internet?
The Internet Protocol makes it possible for you to communicate in various
ways, find things that interest you, and exchange information and files.
The most common things you can do are:
- Send and receive mail with people all over the world. Almost as fast
as the telephone, there is never a busy signal, and you never play
phone tag.
- Join in discussion groups about a common subject with Usenet
Newsgroups and email discussion lists.
- Get or exchange software and files with File Transfer Protocol
(FTP).
- Connect to thousands of different computers using Gopher menu
systems, which make navigation from one site to another easy.
- Explore the World Wide Web (WWW), which can use all of the above.
What are Internet Addresses?
There are two types of Internet addresses—domain addresses made up of
words separated by dots (for example, world.std.com), and IP addresses
made up of four numbers separated by dots (for example, 199.0.65.101).
Both types represent computer addresses on the Internet, and for many
purposes, either type can be used. Numbered IP addresses represent
specific computers on the Internet. Domain addresses may represent a
specific computer or may be less specific.
How do I address mail?
To send mail, you must know the correct address and fill it in at the To:
prompt. Simple Internet mail addresses consist of a Username, an @ symbol,
and the address, which will consist of at least two words, separated by
periods, For example, this is a correctly formatted address:
To: jsmith@delphi.com
There is never more than an @ symbol in an address. Occasionally, you
will encounter an alternate form of address that uses exclamation points
instead of an @ symbol or one in which there are several levels of
addresses in which one or more % symbols act as secondary @ functions.
How do I find someone’s e-mail address?
Most online services will not give out personal information like e-mail
addresses. On the other hand, some people register them and make them
widely available. Other e-mail addresses are collected from usage.
What are Usenet Newsgroups?
Usenet Newsgroups are discussion groups about a topic that is reflected in
their titles, such as:
comp.sys.ibm.pc.games.adventure or sci.astro.hubble. Many of the
newsgroups have worldwide distribution, and their followers post messages,
properly called "articles", for all to read and respond to. The
"Usernet" part of the title refers to their distribution via the
unix-to-unix network. Strictly speaking, newsgroups are a Usenet, not an
Internet protocol, but they are widely picked up by Internet providers.
What is a URL?
A URL is an Internet or Web address that usually begins with http:// and
is the address or location of a web page. An Internet address (or URL), is
comprised of four parts:
- A protocol name (a protocol is a set of rules and standards that
enable computers to exchange information)
- The location of the site
- The name of the organization that maintains the site
- A suffix that identifies the kind of organization it is (such as
.com for commercial organizations)
For example, the address http://www.yale.edu
provides the following information:
http: This Web server uses Hypertext Transfer Protocol (HTTP)
www This site is on the World Wide Web (WWW)
yale The Web server is at Yale University.
.edu This is an educational institution.
How do I search for information on the Internet?
To search the Internet on any topic one uses a search engine. A search
engine is a starting point which provides a field for typing your search
criteria.
For a list of search engines, use our search page. All search engines provide different results, if you don't find what
you are looking for, or need more additional information, try using another
search engine.
1. From the netptc.net
page click on the blue button in the header titled "Web Search".
2. Select your favorite
search engine
3. Type your search
criteria into the specified field. A simple search example is: airline
tickets
4. Click on "Go" or
"Search" on your screen, or press "Enter" on your keyboard.
How you tell a search engine to search a topic is
important. To learn more about how to use a search engine, click the
following link. http://www.albany.edu/library/internet/search.html
If I want my own web site
does Ponderosa offer web site design?
Ponderosa Internet does not
offer in-house web design and programming development. Here are some tips on
locating a Web designer:
-
Do it yourself! There are
many software tools available and at varied price/feature ranges.
-
Explore the Web and
locate a Web site design that you like, then ask them who their web
designer is. Sometimes the Web designer is listed on the site.
-
Contact your local
Chamber of Commerce to find local Web designers in your area.
-
Prices for professional
Web design can range from, $25 to $130 per hour.
-
Purchase a Web site
design software package and do it yourself. There is a learning curve,
but it is the least expensive option.
What is the World Wide Web?
The World Wide Web is one of the protocols that lets you link to many
sites on the Internet. The basic unit is the page, such as the page you
are now reading. A page can be one or many screens as it displays on your
monitor.
Within the page are links to related pages and other web sites. This
system of embedding links in the text on a page is called hypertext. The
links are distinctive, and vary depending on your browser. With most
graphical browsers, links are underlined and appear in a contrasting
color.
Tim Berners-Lee and others invented the Web at the European Laboratory
for Particle Physics (CERN) in Switzerland. It was originally for text
links only, but as it was further developed, multimedia links were added,
too. Now, you can see pictures, listen to audio links, and see video
links, if your computer and software are set up for them. With the
addition of sound and graphics and fast modems to carry the large sound
and graphics files, the Web soon became the most popular way of linking to
resources on the Internet, replacing gopher, which was invented at the
University of Minnesota.
What is HTML?
HTML stands for Hypertext Markup Language. It is a set of standard codes
used to control layout, fonts, colors, and provide links to other pages.
You can also add artwork, pictures, audio, and video to the page with the
appropriate added files and HTML codes.
What is FTP?
FTP stands for File Transfer Protocol. A protocol is a language that
enables computers to speak to one another. FTP is used to make files and
folders publicly available for transfer over the Internet.
What is a firewall?
Firewall refers to the concept of a security interface or gateway between
a closed network and the outside Internet that blocks or manages
communications in and out of the network. The security may be provided by
passwords, authentication techniques, software, and hardware may provide
the security.
What is flaming?
Writing angry or insulting words about a person. It is most often applied
to newsgroups, but it can apply to mailing lists and other forms of public
messaging.
What information do you give away while Web surfing?
When you visit a web site, some information is automatically available.
Click on this link to the Center
for Democracy and Technology to see the information that is available
to all sites you visit. Be patient; it may take a minute to load your
information.
If you clicked on the link above, you saw that any site you visit could
tell—
- Who your provider is
- Where it is located
- What site you came from
- What software you are using
It can also record information about what you do while you are there, and
perhaps collect further information from you. Many sites want you to
register in order to use their services. You may be asked your real name
and e-mail address, your home or business, your telephone number, you
income level, your interests, and so on. This can be valuable information
for running a business. The information in voluntary, of course, and they
have no way to tell if you are faking the information. Think twice before
giving out such information freely. Think about whom you are giving it to
and what uses they could put the information to. How does your name get on
spam mailings? This is one way!
What are cookies, and should you disable them?
If you clicked on the NY Times link, and it was your first visit there,
you were asked to register and provide some information. If it was not
your first visit and you had already registered, you were probably not
asked to register again. How could they tell that you were a repeat
visitor? The answer is that they planted a cookie on your system with
information about you. When you connected, your cookie files were checked
to see if you were a registered user, and you had elected to store your
username and password in the cookie. This is an example of a persistent
cookie, which remains on your system for a long time. Only the service
that installed the cookie has access to it (beside yourself). It is either
in a cookies.txt file on your browser’s disk drive or in a separate file
of its own. Cookies may or may not be encrypted.
Is e-mail secure?
Whenever you send e-mail, it is relayed through successive sites, and is
theoretically accessible to a couple of dozen or so postmasters and system
administrators, who have access to everything that passes through their
machines. As a practical matter, so many thousands of messages pass
through their machines that the chances of anyone looking at any
particular message are pretty small.
If you are using an e-mail account on your employer’s system, the
courts have said that employers have a right to monitor e-mail on their
systems. You’re probably run a somewhat higher risk of e-mail being read
than you would with a large commercial provider.
On the other hand, suppose you have attracted the attention of an
employer or law enforcement authorities for some reason. It is relatively
easy to set up "sniffer" software to monitor every word of every
message looking for your name or for certain keywords or combinations of
words and to forward all such messages for special attention. If the
organization’s security isn’t good and tight (many places aren’t),
it is also possible for hackers outside the system to set up "sniffer"
software in an e-mail system, too.
What this all adds up to is that unless you have reason to be a
particular target, your chances of having mail intercepted and read is
very small, but still exists.
Are credit cards safe to use on the net?
From the preceding discussion of e-mail vulnerability, you might not want
to send credit card numbers through e-mail. What about using credit cards
with web sties? There was a news story last year about a hacker who
retrieved a credit card number list from a web site’s computer and sent
the card numbers to the owners of the cards to show them how insecure the
net is.
But you take similar risks every time you give your credit card to a
stranger in a store or restaurant or over the phone. You take a risk every
time you throw your credit card slips out in the trash. You risk giving
away your credit card number every time you use it; the risks of using
credit cards on the nets are probably less than every day usage, and the
banks generally cover any losses anyway.
The public has been slow to trust credit card use online, and that is
one major thing that is holding up large-scale electronic commerce.
Many sites provide servers that operate in a secure mode with your
browser to let you send information in safe encrypted form though the web
now. The major credit card companies have recently agreed on standards for
secure transmission of credit cards. Security is going to get a lot better
in the times to come.
Parental Control Software
The use of software to block pornography and undesirable material from
children is a controversial subject. There is plenty of material on the
Internet that presents nudity and sexual activity, both in text and
pictures, although the media has tended to overstress its presence. Some
of this material is clearly obscene by United States legal definitions,
such as pedophilia. Some of it is clearly protected by the law, although
perhaps unsuitable for children to view. Since the Internet knows no
national boundaries, material that is illegal in the US can be retrieved
from other countries where it may be legal. There is little that US
legislation can do to prevent the accessibility of such materials.
The issue of censorship is a highly controversial one. Under the US
Constitution and court interpretations, freedom of speech protects a lot
of material that some find objectionable, particularly for children. The
courts have ruled repeatedly that the goal of protecting children cannot
be used to enact means that will also block materials from adults. Since
it is difficult to impossible to block obscene materials from appearing on
the Internet, and since it is impossible to get agreement on what should
be blocked, action is left to individuals and families to find their own
solutions. Schools and libraries with Internet access also have to deal
with these issues in legal ways.
There are a number of approaches using software that can be used by
parents and schools and libraries to restrict undesirable materials. Some
are based on maintaining a list of sites that should be blocked on the
basis of their content. Since such sites come and go very rapidly, this
approach requires frequent updates to the software to be effective. Other
software uses an on-the-spot evaluation of site content by analyzing
vocabulary to determine what should be blocked. Some software uses a
combination of these techniques.
The criteria used to block sites vary widely from one software package
to another. Some packages are very restrictive, and have fallen under
criticism for blocking too much. Others are designed to give the parent or
administrator maximum control of what is blocked. Do you want to block
sexual material only, or do you want to block out sites dealing with
drugs, violence, and hatred, too? Do you want to restrict language usage
in both directions? Do you want to control newsgroups, FTP sites, chat
rooms, and message bases? Do you want a record of what sites your children
visit?
The link that follows compares
the major software packages available for access control, the platforms
they run on, and links to their web sites. If you feel a need for such
software, examine each of them, and select what best meets your needs.
