Physical connection


Hye guys!!:)
Today i would like to share about physical connection
which is used to connect sending
and receiving devices
These connection include:
=
=
twisted pair cable


 two wires twisted together helps
 to reduce crosstalk and electromagnetic induction.
 While twisted-pair cable is used by older telephone networks 
and is the least expensive type of local-area network (LAN) cable,
 most networks contain some
 twisted-pair cabling at some point along the network. 

=
=
Coaxial cable
this cable has over 80 times
the transmission capacity
of twisted pair cable...
It is able to used to deliver
television signals as well as to connect
computers in network..
So, if this cable didn't exist,the possibility
we cannot watch the TV is high.!!

Fibre-optic cable


 


This type of cable able to transmit data as pulses of light
through tiny tubes of glass.
It has over 26000 times the transmission capacity of twisted-pair cable.
They are more lighter and more realible at transmitting data.
commonly used in telephone lines.


ollaaa??

You guys must be thankful to all these cable
