1. Transmision Media
a. Transmission environments:
Copper
Fibre
Air
Electromagnetic waves
- •Radio waves
- •Microwaves
- •Infrared
- •Laser light (including visible light)
Electric charge
2. Electric Network
In these networks, copper wires are used to transmit an electric charge
In rare cases, aluminium, platinum or gold can be used instead of copper
A electric current is pushed through the wire in a controlled manner
In power cords, the amount of electricity is determined by how much the appliance requires
In network wires/cables, the amount of electricity (or charge) can vary in a wave pattern, called a carrier wave4. Electric Cables
5.Coaxial Cables
6.Unshielded Twisted Pair Cable
7. Electromagnetik Network
8. Airwave Transmision
