commonest medium of communication
the difference between channel and medium is that channel is the form how the message will be while medium is the actual message
Fastest transmission rate would be 802.11n
There is no single definition of the word "communication." However, communication can be defined as the verbal and nonverbal transmission of messages and interpretation of those messages. Mass communication would be based off the same definition, but it would refer more to 1 person addressing a large amount of people through some sort of medium such as a radio, television, or even a social media website such as facebook or twitter.

To be effective and efficient
the substance that energy is transfered through. For example when you hear a sound the transmission medium is air.
broadband - A transmissiontechnique that carries more than one type of transmission on the same medium,
Sound waves require a medium, such as air, water, or solids, for transmission. Light, radio, and infrared waves can travel through a vacuum and do not require a medium for transmission.
No Guy its not.
It will determine the speed, reliability and relative security of the transmission.
physical layer.
Optical fiber
Attenuation distortion is the distortion of an analog signal that occurs during transmission when the transmission medium does not have a flat frequency response across the bandwidth of the medium.
fibre optics cables are used as transmission medium.
Electromagnetic waves, however, in fact the medium for the transmission of electromagnet waves is space, so there really is a medium.
we can use a cell phone for a transmission in network.. dinesh kumar dhaneru
