What are the types of Transmission media?

Signals are usually transmitted over some transmission media that are broadly classified in to two categories.

a)Guided Media:These are those that provide a conduit from one device to another that include twisted-pair, coaxial cable and fiber-optic cable. A signal traveling along any of these media is directed and is contained by the physical limits of the medium. Twisted-pair and coaxial cable use metallic that accept and transport signals in the form of electrical current. Optical fiber is a glass or plastic cable that accepts and transports signals in the form of light.

b) Unguided Media: This is the wireless media that transport electromagnetic waves without using a physical conductor. Signals are broadcast either through air. This is done through radio communication, satellite communication and cellular telephony.
Actually the way through which the information or data is sent from one place to another is called transmission media and there are two types of transmission media :


I have created a presentation for the better explanation of both media. I would like you to check my presentation and i am sure you will like it.
