2. • It's new, it's different, and it's going to change just about everything.
• It's an amazing new Post Office. It's the biggest and best library there's ever been.
•It's the education of the future. It means hope, and empowerment.
•But what exactly The is the Internet? Hardware is the short answer.
• Internet consists of a few hundred thousand server computers and the
telecommunications networks that connect them, using a technology called
"packet-switching" that breaks up digital messages into bits, sends the bits via the
most easily available routes and reassembles them at the other end.
3. The Internet is a global system of
interconnected computer networks that use the
standard Internet Protocol Suite (TCP/IP) to
serve billions of users worldwide.
It is a network of networks that consists of
millions of private, public, academic, business,
and government networks of local to global
scope that are linked by a broad array of
electronic and optical networking technologies.
The Internet carries a vast array of information
resources and services, most notably the inter-
linked hypertext documents of the World Wide
Web (WWW) and the infrastructure to support
electronic mail.
4. • The term the Internet, when referring to the Internet has
traditionally been treated as a proper noun and written
with an initial capital letter.
• There is a trend to regard it as a generic term or common
noun and thus write it as "the internet", without the
capital letter.
• The word Internet can be shortened to Net.
• The term cloud is also for the Internet, especially in the
contexts of cloud computing and software as a service.
5. • The terms Internet and World
Wide Web are often used in
everyday speech without much
distinction.
• However, the Internet and the
World Wide Web are not one
and the same. The Internet is a
global data communications
system. It is a hardware and
software infrastructure that
provides connectivity between
computers.
• In contrast, the Web is one of
the services communicated via
the Internet.
• It is a collection of
interconnected documents and
other resources, linked by
hyperlinks and URLs.
7. • The Internet is allowing greater
flexibility in working hours and
location, especially with the spread of
unmetered high-speed connections and
web applications.
• The Internet can now be accessed
almost anywhere by numerous means,
especially through mobile Internet
devices.
• Mobile phones, data cards, handheld
game consoles and cellular routers
allow users to connect to the Internet
from anywhere there is a wireless
network supporting that device's
technology.
• Within the limitations imposed by
small screens and other limited
facilities of such pocket-sized devices,
services of the Internet, including
email and the web, may be available.
• Service providers may restrict the
services offered and wireless data
transmission charges may be
significantly higher than other access
methods.
8. • Examples of personalized marketing
include online communities such as
MySpace, Friendster, Facebook,
Twitter, Orkut and others which
thousands of Internet users join to
advertise themselves and make friends
online.
• Many of these users are young teens
and adolescents ranging from 13 to 25
years old. In turn, when they advertise
themselves they advertise interests and
hobbies, which online marketing
companies can use as information as to
what those users will purchase online,
and advertise their own companies'
products to those users.
• The Internet has also become a large
market for companies; some of the
biggest companies today have grown by
taking advantage of the efficient nature
of low-cost advertising and commerce
through the Internet, also known as e-
commerce. It is the fastest way to
spread information to a vast number of
people simultaneously.
• The Internet has also subsequently
revolutionized shopping—for example;
a person can order a CD online and
receive it in the mail within a couple of
days, or download it directly in some
cases. The Internet has also greatly
facilitated personalized marketing
which allows a company to market a
product to a specific person or a specific
group of people more so than any other
advertising medium.
9. • The Internet is changing the way
we think.
• It's the first medium that isn't
passive: Internet users are far more
assertive than TV viewers, and it
becomes a habit.
• Less and less do Internet users fit
the cozy idea of communities as
mere "markets" of passive
consumers.
• As everywhere else, sharks and
predators prowl the murkier depths of
cyberspace, sleaze seeps through the
seams, and it tends to obscure the
many healthy trends.
• Communication is healthy -- it breaks
down barriers, and with the Internet
more people are communicating more
than ever before: 750,000 messages a
day are posted on the Usenet
newsgroups alone, and email and chat
lines account for much more than
that.
10. •The level of cooperation, the kindness and generosity Internet groups show to
newcomers and each other, the immense trouble people -- many people -- will
go to, without pay or reward, to make better resources available and to help
people they don't even know, all expose the "marketplace" and the idea that
people are only motivated by greed and self-interest as the sheer nonsense it
always was.
•And the levels of maturity, fairness and responsibility so many Internet groups
demonstrate in their self-administration and general conduct is a strong counter
to the idea that communities need Nanning authorities to tell them what to do.
