Berlo's Model of Communication (SMCR Model) - Communication Models Berlo's SMCR Model of Communication was proposed in 1960 by David Berlo and describes the communication process in it's most basic form. It has four communication components in it which are Sender, Message, Channel and Receiver. The components are affected by various factors and that's how the communication process is done. Encoding and Decoding of message is also done in this type of model. The four components defined are: SENDER Sender is the person or the source that sends the message to the receiver. It's the place from which the communication process starts or originates. There are multiple factors which affect the Sender and they are: Communication Skills:  One of the most important factor, if the person who sends the message has good communication skills then the message will be communicated better than if the person doesn't have good communication skills. Good communication s...

Shannon and Weaver Model of Communication This model of communication was proposed in 1948 by Shannon (Electrical engineer and American mathematician) and Weaver who was an American Scientist. They both together wrote an article called as "A Mathematical Theory of Communication", more popularly known as the "Shannon and Weaver Model of Communication". There are 5 concepts in this model of communication: * Sender is the person who sends the message, basically the source of the message * Encoder is the person or transmitter who uses technical machines to convert the message into binary data or signals * Decoder is the place where signals or binary data is converted back into message. It is the opposite of Encoder * Receiver is the person who gets the message sent by sender * Noise : Physical disturbances caused in environment like crowd noise, horns, thunder etc. or disturbances caused during transmission process. This model was designed for effect...

Magic Bullet Theory (Hypodermic needle model) Magic Bullet Theory, also known as Hypodermic needle model or Hypodermic-syringe model is one of the communication models which was proposed by Harold Laswell and was originally written in the book "Propaganda Technique" during the World War. Magic Bullet Theory says that media's message is a bullet fired from the media gun to the people's head. It means that media fires or injects message or different messages into the audience like a bullet and the audience believes in what they are seeing or hearing from the media. Magic Bullet Theory says that the audience is passive and they are dependent totally on the media to know about what is happening around them and the world and the media keeps on injecting the media's message to the passive audience like a syringe or shooting into their head like a bullet. Masses of people are made to think as the same way media wants them to think and create public opinions and ...
