Communication Media
There are a wide variety of communication media being used today. Each has its own capabilities and limitations. Here are some of them:
Twisted Pair Wire
It is compose of two intertwined copper wires coated with plastic. They are bound together in another layer of plastic insulation. It is widely used in telephone connections. This is one of the widely use communication media because it is inexpensive and commercially available.
Coaxial Cable
Commonly known as “coax” usually used in cable T.V, These tables have two conductors, the first one is a single piece of wire in the center. The other one is a shield that surrounds the first wire with an insulator between. Coaxial cable can carry more data than older types of twisted-pair wires because of its unique shielding.
Fiber Optic Cables
Instead of transmitting frequencies, a fiber optic cable transmits pulsating beams of light. Compared to te twisted pair wire and the coaxial cable, fiber optic can carry a greater volume of data since light travels much faster than electricity. This type of cable is also immune from electromagnetic interference which is a problem for copper based mediums. However, fiber-optic cables is relatively expensive compared to other mediums and is not as flexible as copper based medium.
Wireless Links
The use of wires and other physical media seem to be impossible and impractical because of “distance”. For example, how would you connect two places separated by a mountain range or an ocean?.
