    Randomness:- Randomness plays vital roles in communications. Noise is one of limiting factors that comes in communication in the random signals. Randomness is combined with informations. Randomness means uncertainty ,unpredictability of outcomes. Information is combined with probability and probability is associated with information. If persons winks it conveys some information to the content. If persons were winks regularly there is no meaning of information. Unpredictability is what which gives the full information.

    Redundancy:- Redundancy also plays vital roles in communication. It is reliable for communicating with some information. Due to redundancy we can decode the message without getting errors in received message. It is helps to minimise the noise. Redundancy help to combat noise in the message. A deliberate redundancy is take action to reduce the noise.

    Coding:- Coding plays important role in modern communication systems. Error coding is more effectives in digital communication because of cost- effectiveness and reliable for the transmission of Data. Error control coding is methods deliver message from source to destination with less error. Error coding is categorised with forward error correction(FEC)and automatic repeat request(ARQ) or combination of both.
