What is media:-
· A network needs
physical medium to connect its nodes together.it decides that is where the data
actually flows.
· There are three types
of MEDIA:-
-Coaxial Media
-Twisted Pair Media
-Fiber Optic Media
1.
Coaxial Media:-
·
It
contain a solid or stranded wire in the core that is insulated with a
dielectric layer, then protected with a solid or braided metallic shield, &
covered with an outer insulator.
· Electromagnetic
wave propagation in a coaxial cable is confined within the space between the
core & the outer conductors.
· It
is used to small connectivity because it is less susceptible to interference
noise.
