HISTORY OF COMMUNICATION
O
riginated in the need for human self-protection.
T
he desire to pass more complicated.
F
inally, mankind has finally started electricity to
communicate.
RADIO
Loudspeakers to convert the sound into
a radio wave, for the modulation of a
high frequency current.
In 1919, Marconi radio transmitter in the UK Kerr Chelmsford.
A major role in past communications, sent to Earth on space situation and the transmission of information between the two places on Earth.
FIBRE ERA
Is capable of transporting the light
fiber. It smaller than cable, only slightly
thicker than a human hair.
ADVANTAGE
(1) large capacity communication
(2) long distance relay
(3) from electromagnetic interference
(4) resource-rich
(5) fiber optic light weight, small size
CONCLUSION
(1) Optical fiber will gradually become part of our daily life.
(2) Optical fiber small size, light weight, ease of laying and
handling of raw materials.
(3) In addition, fiber is a very wide range of applications, so
gradually replace copper as the main medium of
communication.
