4. • Definition - What does Communication
Media mean?
• Communication media refers to the means of
delivering and receiving data or information.
• May be in telecommunication.
The term is also commonly used in place of
mass media or news media.

5. Media Communication.
Media whether its contains wires or it is
wireless allows two or more people to
communicate with one another without
being physically present.

7. • Twisted Pair cable:
• A twisted pair wire is a copper wire that
connects your personal computer to the
telephone line.
• It is called a twisted wire because two
wires that are insulated to prevent wire
crossing are twisted together.

9. Coaxial Cable:
• is also known as a co-ax. This design
provides the coaxial cable with a special
advantage: electrical interference is reduced
because the two conductors are shielded and
confined separately.
• cables are used primarily for TV standard-
definition connection to transfer television
signal, and for internet connection. Because, it
might carry much more data. Also, it is used
to carry radio signal, video signal, and
measurement signal.

10. Cont…
• Coaxial cable was invented in 1929 and
first used in AT&T established its first
coaxial transmission system in 1940.
• The speed of coaxial cable is depended on
the carrier used technology and other
factors.
• The Twisted Pair cable and Fiber Optic
cables are alternative to the Coaxial cable.

12. Fiber Optic Cable:
fiber optic has become one of the most
technological advances to transmit
information.
It transmit the data by using the luminous
pulsations.
And this transition is transmitted without
interruption.
Because the luminous transitions is by light
not by electricity.

14. Wireless Communication:
History
The birth of wireless
communications dates
back to 1901 when
M. G. Marconi successfully
established a radio link
between a land-based station
and a tugboat.

15. Infrared (IR) wireless communication:
IR wireless communication communicates data
or information in devices or systems through
infrared (IR) radiation. Infrared is
electromagnetic energy at a wavelength that is
longer than that of red light.

16. • Basically an audio broadcasting service, radio
broadcasts sound through the air as radio
waves. It uses a transmitter to transmit radio
waves to a receiving antenna.
• A radio broadcast sends data over long distances
(across countries) at up to 2 megabits per second
(AM/FM Radio).

17. Microwave Radio:
• Microwave transmission involves the transfer of
voice and data through the atmosphere as
super high-frequency radio waves called
microwaves. Microwave transmission is mainly
used to transmit messages between ground-
based stations and satellite communications
systems.

18. Communications Satellites:
• A communication satellite is an artificial satellite used
specifically as a communication transmitter/receiver
in orbit. Data is passed through a satellite using a
transponder which is a signal path. Most satellites
have between 24 to 72 transponders, with a single
transponder capable of transmitting and receiving
155 million bits of information per second. This huge
capability makes communication satellites an ideal
medium for transmitting and receiving all kinds of
content, including audios and videos.
