The document discusses six networks that have changed communication over the past 200 years: 1) The cable network established in 1835 with the telegraph, allowing electrical pulses to be transmitted through cables. 2) The broadcast network enabled electromagnetic signals to be broadcast through the air and received by many receivers, including early radio and television. 3) The exchange network began with telephone switchboards connecting multiple phone lines. 4) The constellation network started with the Telstar 1 satellite enabling live television signals to be transmitted across oceans. 5) The cell network featured early antennas disguised as cacti that transmitted radio waves to enable mobile phone communication. 6) The web network originated in the 1970s with connections

2. Information Age
Six Networks that changed our world
Our messages from the mundane to the
memorable_ can be counted, compressed and
reduced to fundamental ‘bits’. This is information.
Information Age tells the story of 200 years of
information and telecommunication networks.
Across six networks, it reveals the hidden
infrastructure and devices that have allowed us to
send more information further and faster than ever
before.
Through 21 transforming moments, it presents the
extraordinary people who have created, used and
been affected by each new wave of technology

o The CONSTELLATION network
o The CELL network
o The WEB network

4. I. The cable network
by Joris and Arthur

6. It was created in 1835.
Telegraph networks send information from
point to point in the form of electrical
pulses.
Pulses sent from Morse keys travel throught
cables and are received by Morse sounders.
The science museum think this object is
important because this one began the era of
the network.

7.  The telegraph is the transmitter in the
communication network :
Transmitter
Signal
Receiver

8.  This invention has changed people’s lives because this
one enable to send a message and receive it quite
quickly.
 … And to communicate faster on long distances.

9.  Morse code (with energy pulses)(.. / .-.. --- ...- . / .--. ---
- .- - --- . ...)
 A telegraph line
 Stop:
.-. --- -.-- .- .-.. / -... .- -... -.-- / -... --- .-. -. / ... - --- .--. / -.-
. .... .- .-. .-.. --- - - . / ... - --- .--.

10.  The limits on our messages are the way we
communicate because we must give the essential
information.
 But we can’t make or maintain human relationships.

11. II. The broadcast network
by Mathis and Virgile

12. AMPEREMETER?
PHONE?

13. Information
is carried by
electromagnetic signals.

14. Signals sent out from
transmitters travel
through the air and
are picked up by
many different
receivers

15. Transmitter
Receiver: lke TV

16. … today, pupils can know piece of news
just in some minutes.

19. People get very
equipped

20. Transmitter

21. People became…….

24. PEOPLE
BECAME
DEPENDANT!!

25. III. The exchange network
by Jennyfer and Milaan

26. Was it used to speak with others?
The wooden thing
to speak …
Numbers …

27. - System used to connect telephone calls
with many separate phone.
- One of the oldest switchboards still in
existence
- Beginning of the exchange network and
people being connected together.

28.  Communication networks need three elements:
…………………………………………..
TRANSMITTER
SIGNAL
RECEIVER

30. IV. The constellation network
by Bertille and Mathilde

31. -A satellite ?
- a model ?
- a UFO ?

32. The satellite Telsar 1
Used to
share the
television
between
Europe and
the USA.
It is the first time a television program could be
directly transmitted in Europe and in the United
States at the same time.

33. Communication
Signal
Transmitter Receiver
Teslar 1 is a Receiver and a
Transmitter.

34. People’s lives
Telsar has changed people’s lives
because the information can go faster
with it and they can receive the
pictures.
Now the whole planet could distribute
pictures everywhere in real time.

35. Satellites…
Satellites like
NASA satellites
are used for the
phone or GPS
and TV
transmissions.
Communication-Modernity-International

36. If all the satellites
disappeared…?
The world will plunges into a
total black, nobody being able
to communicate with nobody.
GPS, television, telephones , the
maritime radars and the control
towers of airports would not be
usable, engendering numerous
dangers.

37. V. The cell network
by Sacha, Lothaire and Gautier

38. A cactus ? With something
inside ? It seems to be old and it should
be used to protect the thing inside and
to look nice
 An old antenna ?
 It was used to
transmit radio waves ?
Because the thing inside seems to be used
for it and because it was located in the cell
network

39.  This objet is an antenna like I thought
 It was used to transmit radio waves like I thought
 It is important because it’s beautiful to see and
difficult to differentiate from other cactus and it allows
peoples to phone.

40.  I think this is both an transmitter and a receiver

41.  This object has changed people’s life because they
could phone to other people, even if they were in very
foreign countries. All the very interessant things that
happens in town could be transmited to them.

42.  Three words could be picked up : phone, transmittion,
cact

43. Phone
Transmission
Cactus

44.  We don’t think that communication
technology spoils the environnement
because communication is the base of
the human society.
 We must consider gradualy the
environnement

45. VI. The web network
by Eulalie, Alexandre, Simon

46. electrogardiogram a printer
sound waves emitter
strong-box

47.  What was it used for ?
In 1973, perter Kirstein
connected University college
Londo to the ARPANET, the
world’s first packet-switched
computer network. Throughout
the 1970s and 1980s Kirstein
helped move sprawing and
incompatible computer
networks onto the protocols
that gave rise to the global
internet as know it today.

50.  Information was transmitted faster

51. Revolution

52. The Internet can make us smarter
because it can be useful to learn more and
more things about life and lessons.
