Elaborate transactional model of communication with proper diagram. 

Transactional Model

The transactional model shows that the elements in communication are interdependent. Each person in the communication act is both a speaker and a listener, and can be simultaneously sending and receiving messages.
There are three implications in the transactional model:
i.    Transactional‖ means that communication is an ongoing and continuously changing process. You are changing, the people with whom you are communicating are changing, and your environment is also continually changing as well.
ii.    In any transactional process, each element exists in relation to all the other elements. There is this interdependence where there can be no source without a receiver and no message without a source.
iii.    Each person in the communication process reacts depending on factors such as their background, prior experiences, attitudes, cultural beliefs and self-esteem.
Transactional model of communication takes into account noise‖ or interference in communication as well as the time factor. The outer lines of the model indicate that communication happens within systems that both communicators share (e.g., a common campus, hometown, and culture) or personal systems (e.g., family, religion, friends, etc). It also takes into account changes that happen in the communicators‘ fields of personal and common experiences. The model also labels each communicator as both sender as well as receiver simultaneously.
