45 years ago The Internet was born
A brief history of communications
People started to publish
3. In the 1960s, a U.S. defense research project created a linked network that
shared information across computers.
The Internet
It was a network
called
ARPANET.
It relayed data from
one computer to
the
next using packet
switching
technology.
4. The World Wide Web
25 years ago Tim Berners-Lee invented the World Wide Web
It was an open platform of standards
where anyone could create a Web site
on
the Internet.
Opening up the platform for everyone
was
the catalyst for explosive growth.
The Internet grew
to become one of the largest
structures
ever assembled by humans.
5. It exploded in all directions
In 1995 there were an estimated 16
million "active Internet users"
worldwide representing only 0.4 %
of the world's population.
As of 2014, the number of internet users
worldwide is about2.92 billion.(40 % of the
population).
6. Growth Of Internet In India
Presently Over 200 Million Users
Indian Internet users will surpass the number in the U.S. by the end of this
year and around 500 million people will be online by 2018.
10 years –From 10 million to 100 million Internet users. Now the country
is adding five million new Internet users every month.

9. The Internet age is a major historical shift. Like the industrial revolution, it is
changing nearly every aspect of life:
political systems
economic power
gender roles
where and how we live
And the most important thing about the Internet: It was all built on a
level playing field called Net Neutrality.
how we liveThe Internet is changing
10. Welcome to the revolution
Net Neutrality is this:
Net Neutrality is the guiding principle that
preserves the free and open Internet.
It ensures that all users can access the content
or run the applications and devices of their
choice.
Under Net Neutrality, the network's only job is
to
move data — not choose which data to
privilege
with higher quality service.
11. Here’s how it works
The Web flows into your computer through
pipes owned for the most part by phone and
cable companies.
They charge fees to anyone who wants to
use them, but they're not allowed to mess with
what's inside those pipes.
Net Neutrality ensures that everyone’s Web
sites gets treated the same.
12. Net Neutrality saves democracy
I can read my cousin's political blog just as easily as I
can
browse to CNN.com.
I can download music from a independent music site
as easily as I can from Sony’s Web site.
I can post a video of a local campaign speech
confident
that network owners won’t impede access to it.
Since the Internet's birth, every site, every packet of data,
regardless of its size, has been given equal — neutral —
treatment by providers; its content is transmitted at
equal speed:
Under Net Neutrality, users choose
13. Net Neutrality is the Internet …
This fundamental notion of an open and level playing field is NOW under
siege by powerful industries who seek to tilt the field to their advantage.
Net Neutrality is the reason that the Internet has
been an explosion of online economic innovation,
democratic participation, and free speech.
... and it’s now under threat
14. What happened to stifle openness and limit
access to broadcasting is happening to the
Internet right now.
… could happen to the Internet
A handful of phone and cable giants are
promising to build a new network of Internet
services. But they want something in return
from government. They want control. Not just
over the “pipes” but control over the Internet
itself.
They’re pushing laws that
would gut Net Neutrality
15. Google users—Another search engine could pay dominant Internet
providers like AT&T to guarantee the competing search engine
opens faster than Google on your computer.
Ipod listeners—A company like Comcast could slow access to
iTunes, steering you to a higher-priced music service that it owned.
Political groups—Political organizing could be slowed by a handful
of dominant Internet providers who ask advocacy groups to pay
"protection money" for their Web sites and online features to work
correctly.
Online purchasers—Companies could pay Internet providers to
guarantee their online sales process faster than competitors with
lower prices—distorting your choice as a consumer.
Small businesses—When Internet companies like AT&T
discriminate in favor their own services and allies, new market
entrants won’t be able to compete.
Bloggers—Costs will skyrocket to post and share video and audio
clips—silencing citizen journalists and putting more power in the
hands of a few corporate-owned media outlets.

It has three components
1) Client computers
2) Distributed Servers
3) Data centers
21.
22. Why cloud service is popular?
Reduce the complexity of networks.
Do not have to buy software licenses.
Customization
Information at cloud are not easily lost.
Unlimited Storage Capacity
Increased Data Reliability
Free From Maintenance
Instant Software Updates

24. What is project loon?
Many of us think of the Internet as a global community. But
two-thirds of the world’s population does not yet have Internet
access. Project Loon is a network of balloons traveling on the
edge of space, designed to connect people in rural and remote
areas, help fill coverage gaps, and bring people back online
after disasters.
29. ENVELOPE
Project Loon’s balloon envelopes are made from sheets of
polyethylene plastic and stand fifteen meters wide by
twelve meters tall when fully inflated.
A parachute attached to the top of the envelope allows for a
controlled descent and landing whenever a balloon is ready
to be taken out of service.
30.
31. SOLAR PANELS
Each unit’s electronics are powered by an array of solar panels
that sits between the envelope and the hardware.
In full sun, these panels produce 100 Watts of power - enough
to keep the unit running while also charging a battery for use
at night.
By moving with the wind and charging in the sun, Project Loon
is able to power itself using only renewable energy sources.
32.
33. EQUIPMENT
A small box containing the balloon’s electronic equipment .
This box contains circuit boards that control the system .
Radio antennas to communicate with other balloons and with Internet
antennas on the ground.
And batteries to store solar power so the balloons can operate during the night
.
34.
35.
36. The Pilot Test
Project Loon has started in June 2013 with an experimental pilot
in New Zealand.A small group of Project Loon pioneers will test
the technology in Christchurch and Canterbury.
30 balloons have been launched from New Zealand's south island.
The experience of these pilot testers will be used to refine the
technology and shape the next phase of Project Loon.
37.
38.
39. The technology
Project Loon balloons float in the stratosphere,twice as high as
airplanes and weather.
They are carried around the earth by the winds and they can be
steered by rising or descending to an altitude with winds
moving in the desired direction.
People connect to the balloon network using a special Internet
antenna attached to their building.
The signal bounces from balloon to balloon,then to global
Internet back on earth.
40.
41.
42. How loon moves with the wind?
Project Loon balloons travel around 20 km above the Earth’s
surface in the stratosphere. Winds in the stratosphere are
generally steady and slow-moving at between 5 and 20 mph,
and each layer of wind varies in direction and magnitude.
Project Loon uses software algorithms to determine where its
balloons need to go, then moves each one into a layer of wind
blowing in the right direction. By moving with the wind, the
balloons can be arranged to form one large communications
network.
43.
44. how loon connects?
Each balloon can provide connectivity to a ground area about 40
km in diameter at speeds comparable to 3G(around 10 Mbps).
Each balloon is equipped with a GPS for tracking its location.
There are 3 transceivers:balloon-to-balloon,balloon-to-ground
and third for backup.
The balloon use antennas equipped with specialized radio
frequency technology.
Project Loon currently uses ISM bands(specifically 2.4 and 5.8
GHz) that are available for anyone to use.
45.
46.
47. Ism Bands
ISM bands stands for Industrial,Scientific and Medical bands.
Radio bands reserved internationally for the use of radio
frequency(RF) energy for industrial,scientific and medical
purposes other than communications.
In general, communications equipment operating in these bands
must tolerate any interference generated by ISM equipment, and
users have no regulatory protection from ISM device operation.
51. INTERNET
OF THINGS
The Internet of Things (IoT) is a scenario in
which objects, animals or people are
provided with unique identifiers and the
ability to transfer data over a network
without requiring human-to-human or
human-to-computer interaction.
