Claude Shannon's Model is also known as telephone model. The message is not necessarily delivered to it's destination because of the intervention of the noise. This model gives us the concept of 'noise'. It has 5 models, the information source that makes the message, next is the transmitter that transmit the message and next is the signal (recieves the message wherein the noise is attached), next is the reciever that recieves the signal and next is the destination of the message.
