About transmission media ?

                  For this section , I will talk about transmission media. What is it with transmission media? As Shelly Cashman said 'Material or substance capable of carrying one or more signals in a communication channel.'. 

                  There are two types of transmission media which are physical transmission and wireless transmission. For physical transmission there are Twisted-Pair Cable, Coaxial Cable and Fibre Optic Cable while for wireless transmission there are Infrared, Broadcast Radio,  Cellular Radio, Microwave and Communications Satellite.
