"Beam me up, Scottie." This popular line from Star Trek
was a demonstration of the advanced technology of the future. Though it was a
fictional story, Star Trek became the universal vision of the future. As always
reality tends to mimic fiction. Though our society has not quite resulted to
living in space, we have made life easier with technology. Economic survival
has become more dependent upon information and communications bringing forth
new technology of which was never thought possible. Just a mere thirty years
ago a computer occupied a whole room compared today’s palm sized computers,
which are faster and perform more functions. Cellular phones, now light and
compact, were bulky just ten years ago. The most incredible invention, the
Internet, is bringing infinite amount of information to your desktop. In the
world of the of the Internet there exist a world blind to skin color and other
physical appearances. The Internet while still young in age has grown rapidly,
spreading to countries world wide and connecting 50 million users. With its
popularity, it is incumbent upon our society to recognize how the Internet
works and to be aware of its advantages as well as disadvantages. While
seemingly high tech the Internet concept is rather simple. Computers speak to
one another and send information. This is accomplished by sending and receiving
electronic impulse, and then decoding them into a message. In order to
communicate with one another they are linked up in a network. They are then
able to access information from thousands of other computers. The network acts
like one large computer storing information in various places, rather than in
one physical structure. Users tap into the Internet to access or provide
information. Internet technology allows one to surf the World Wide Web or send
e-mail. The vision of the Internet that would revolutionize the computer and
communications belonged to JCR Licklider of MIT (Leiner n. page). In August of
1962 he envisioned a globally interconnected set of computers which would allow
everyone to quickly access data and programs (Leiner n. page). A government
sponsored project at Defense Advanced Research Projects Agency (DARPA) started
in October (Leiner n. page). The race for discovery of such technology raged
between the Soviet Union and The United States of America. Both countries
wanted control of the possibly powerful tool. Then in 1968, The National
Physical Laboratory in Great Britain set up the first test network, which
prompted the Pentagon’s ARPA to fund a larger project in the USA. (Sterling n.
page) However the race was not limited to just nations but also companies. In
1965, working with Thomas Merrill, Lawrence G. Roberts created the first
wide-area computer ever built. These experiments proved that computers could
work together running programs and retrieving data as necessary on remote
machines. Roberts put together his plan for ARPANET, published in 1966. At that
time he learned of Donald Davies and Roger Scantlebury of NPL and Paul Baron
and others at RAND. Research at MIT (1961-1967), RAND (1962-1965) and NPL
(1964-1967) while parallel had no knowledge of one another. In August of 1968
an RFQ, a refined model of ARPANET was released for the development of one of
the key components, the packet switches Interface Message Processors (IMP).
Bolt Beranek and Newman (BBN) installed the first IMP at UCLA and the first
host computer was connected. By the end of 1969 four host computers were
connected together into the initial ARPANET and the Internet was off the
ground. In 1977, electronic mail was introduced. (Leiner n. page) As the Internet
quickly grew, changes were necessary. The Internet’s decentralized structure
made it easy to expand but its NCP did not have the ability to address networks
further down stream than the destination IMP. Bob Kahn decided to develop a new
version of the protocol which eventually became known as the Transmission
Control Protocol / Internet Protocol (TCP/IP). Compared to the NCP which acted
as a device driver, the new protocol was more like a communication protocol. In
order to make it easier to use, Host were then assigned names, replacing
numbers. A group of scientist then set out to show that a compact and simple
implementation of TCP was possible. They succeeded, allowing it to run on
desktop computers. (Leiner n. page). Original uses of the Internet included
government communications and a forum for scientist to share ideas and help one
another in research. In the 1980’s the Internet grew beyond its primarily
research roots to include a broad user community and increased commercial
activity. In present day it has become a tool for conducting research and
finding information, as well as communications with others. Electronic mail,
amazingly popular, with chat rooms and discussion groups makes the Internet a
popular place for meeting new people. (Leiner n. page). Perhaps the largest
shift is in the profile of Internet users. In the beginning users were
scientist and government officials: those highly educated and well trained.
However today’s 50 million users are all ages and from all backgrounds (Why use
the Internet? n. page). Access to the Internet is no longer limited and can be
found just about everywhere including schools, colleges, libraries, and at
home. In 1992 the Internet had a growth of twenty percent every month (Why use
the Internet? n.page). A developer of the Internet said, "If the Internet
stumbles, it will not be because we lack for technology, vision, or motivation.
It will be because we cannot set a direction and march collectively into the
future." (Leiner n. page) Clearly the Internet has brought many
conveniences. Businesses and students benefit from the technology as well as
those who use the Internet for personal uses. Over 50 million people used the
Internet in 1995 and by the year 2000 the number is predicted to be over 150
million (Why your company should be on the Internet n. page). Fortune Magazine
said, "The Internet is the biggest and earliest manifestation of the way
business is going to be conducted from now on." Companies are embracing
the Internet and those who do not will be left behind (Why use the Internet? n.
page). The Internet opens a wider audience to companies providing customers
valuable information via mailing lists. Space on the Internet is inexpensive
compared to paper, radio and television advertisements, therefore companies
reach a broader community with little cost (Why use the Internet? n. page).
Most web users are well educated Americans with professional or technical jobs
with median annual salary of $69,000, making them a prime target group. Opening
a storefront online gives the advantage of always being open. The Internet is a
fair playing field for large and small companies alike. Computer networks track
inventory and consumer demand resulting in increased profits (Why Minnesota
Students Need Access to the Internet n. page). Remote video conferencing and
Internet phones allow companies to conduct live chat sessions with clients
around the world. Data bases are available for public or private uses.
Companies can transfer files, bulletins or e-mail via the Internet, and it is
all very affordable.(Why use the Web? n.page) Students as well as commerce is
benefiting from the Internet. Students need more information than is offered by
school libraries. The Internet gives students access to resources from around the
world. They are also more willing to sit and browse the Internet then to use
the library. Information can be found, selected and retrieved faster on the
Internet. Entire books can be transferred in minutes (Sterling n.page).
Students find the Internet to be a viable educational tool which makes them
aware of the globalism of the world rather than sheltered in the realm of the
classroom. They have the option of writing to pen pals in other countries and
getting to know other cultures. (MRP-Discussion n. page) The Internet also
serves as a preparation tool for the future. The world is moving towards
electronics: in today’s market being competitive means knowing how to get
information, and more and more, it is traveling by wires. The Internet allows
children to get hands on experience, and helps them develop intellectual skills
and problem solving. It allows children to research information that interest
them. For example, a child interested in baseball can find information on the
latest statistics and read about the history of the sport. By educating
themselves it opens their minds to technology. (Why Minnesota Students need
access to the Internet n.page) The Internet is a popular place to socialize.
Exchanging information with those far away take only seconds using the
Internet. While postal mail can take days, electronic mail, or e-mail, takes
seconds. Many companies offer e-mail services for free to those with access to
computer with a modem. Unlike phone system and postal system there are no
charges for long distance service or communication with foreign countries.
E-mail and instant messages (found in programs such as America Online and ICQ)
can be used to send images and software. (Sterling n. page) Internet technology
has gone as far as to allow people to make new friends without any physical
contact. One way to meet new people is to join an Internet discussion group. In
such a group people with a common interest ask and receive advice and exchange
information. Another opportunity to meet new people is in Internet chat rooms.
In such rooms one can speak freely to anyone as if they were at a party.
America Online users refer to relations charter though the sever as "AOL
luv". Those in discussion groups and chat rooms are not limited to just
Americans but open to people all around the world. The Internet is a world wide
tool filled with many cultures, and different people. In this world, race is
not a factor since there is no physical contact. Everyone is equal and has the
freedom to express oneself. It is an institution that resists
institutionalization. It belongs to everyone and yet no one, everyone sort of
pitches in and it evolves on its own. There are no censors, bosses, board of
directors or stockholders. The Internet is unregulated and uncensored. However,
the Internet being so free and uncensored presents many problems.
Acknowledgment of children using the Internet has fueled a fight for
regulation. Parents can not always monitor their children, therefore the
Internet needs to be a safe place for the children. Children have access to the
Internet in schools, libraries, and just about everywhere. In schools it is
nearly impossible for a teacher to watch all the children, and in libraries it
is not the librarian’s job to monitor them. Computers and the Internet are for
everyone, including children, thus it has become an immense problem. Access to
pornography has been one of the greatest concerns among parents. Surprisingly,
pornography is easy to access and children will. Children are naturally curious
and love to explore. Minors are also targeted by advertisers. Just like on
television advertisers try to lure children in with pictures and web sites
which include games and chat rooms. However the biggest danger is not what they
find on the Internet but who they find. The information they access is not as
dangerous as the people they meet. There have been many cases of molesters and
kidnappers searching for pray on-line. Nicknames are used to protect the
identity of the children but can also be used to mask adults. They enter
children’s chat rooms and coax the children to trust them. Nonetheless, denying
the children access to the Internet is not the solution, perhaps software is.
However software limiting children’s access to web pages have not been
successful. In some case the software does not filter out all inappropriate
pages but filters out non-objectionable pages. (Should children be kept
off-line? n.page) Molesters and kidnappers are not the only people with access
to the Internet we should fear. Those mischievous thinkers also pose a threat.
Known as hackers or crackers, they search for vulnerable computer systems then
strike. Businesses can lose trade secrets, and the damages can be a disaster.
In 1996 Dan Framer, a security consultant, tested 2,000 computers networks, and
of those 65% had security holes large enough for an intruder to enter (Freedman
280). Government computers are just a vulnerable as teenagers have recently
demonstrated. Teenagers working out of their home with guidance from a 18 year
old broke into government classified information. Though they were caught, it
bought alarm to the possible dangers of information leaks. The United States’
enemies could have access to military codes and top secret files. Although the
average person is not targeted by hackers they are in danger of fraud and
con-artists. Stolen credit card numbers have been rumored to be a major
problem. The chances of it happening are not as great as the media makes it to
be, but nevertheless it is a problem. The criminals easily get away with such a
crime. They get the number of a credit card and charge ridiculous bills, but by
the time the bill comes they have moved on to the next victim. Many schemes
come in the form of junk mail. They offer deals that sound too good to be true
and chances are they fake. They only ask for a small sum of money up front,
next they cash the check and move on. (Anarchy Online 98) Secure passwords can
prevent hackers from accessing computers. Passwords should consist of numbers,
letters and symbols: an example "P11++69." No matter how secure and
high tech the computer security system, all it takes is a simple, stupid
password like "hello" to render the whole system worthless. (Freedman
279) Though the Internet has its advantages it also has disadvantages,
therefore users should educate oneself on the revolutionary tool. With over 50
million users the Internet is rapidly growing and is to the ‘90’s what the
personal computer was to the 70’s. New usage’s are springing up everyday,
making it impossible to predict the future of the Internet. One thing certain
is that the Internet has revolutionized the computer and communications.
"The Internet is a world wide broadcasting capability, a mechanism for
collaboration and interaction between individuals without regard to geographic
location."
