COAXIAL CABLE

There are many cables used in any network for communication. First of all we will take a look at Coaxial cable.
Coaxial cable is a kind of copper cable used by the cable TV companies between the community antina and user's home. This cable was invented in 1880 and invented by Oliver Heaviside.

As you can see in the diagram the cable is protected by Plastic jacket. Also Dielectric insulator is used here for protecting the inner interference and the electric signals travel through the central core, means the data is exchanged by the central core.

Coaxial Cable is of Two Types
Thin Net Coaxial Cable & Thick Net Coaxial Cable 

Thin Net Coaxial Cable :- The copper wire is Thin as the name says and the wire has less diameter. The range of this wire is 185 Meter, 10 base 2 , means 200 meter long and have 10 Mbps speed.

Thick Net Coaxial Cable:- This wire is Thick and having more diameter then upper discussed cable. This cable is known as 10 base 5 cable ( 500 meter long and 10 Mbps speed)
