What is the constitutive nature of communication？

The constitutive nature of communication would be it's ability to present a medium for expression and information sharing.With communication, one can impart, exchange or convey messages/ideas/feelings in any form of choice; verbal or written. Communication is a two way process of sharing information, reaching mutual understanding and developing relationships.
Communication as a concept entails a series of recognised phases from when a message is expressed till when it is received. As a process, communication is realised when;a) there are two parties involved; Sender and Receiverb) A message is transmitted, or knowledge is sharedc) there is a channel or Platform for the message transmission or deliveryd) Feedback, or response from the receiver back to sender (this is optional)
Communication is imminent to human activity in the sense that the concept of communication can be linked to every part of a human being's lifetime. For this one reason, the essence of communication cannot be underestimated and a very good understand of its process, types , scope and needs cannot be overemphasized.
Sociologically speaking, the constitutive nature of communication would imply possessing something of value to convey to a receiver. Communication can be seen as the key to the ideas, actions, feelings, impressions etc. we encounter everyday. The media, books, schools are but a few platforms of communication - These platforms helps to facilitate the spread of knowledge and information among people. In a way, one could say that most of the knowledge we possess today are as a result of communication either verbally or non verbally.

Communication is a process by which meaning is conveyed through messages. The messages can be either verbal or nonverbal, and they can be transmitted in a variety of contexts that effect how the message is interpreted and the meaning that is conveyed.
Communication, as a process, consists of the following components.
The source, or sender of the message
The message, or information to be conveyed
The receiver, or the person receiving the message
The channel, or path the message takes from sender to receiver
The feedback, or the information the receiver conveys to the sender in response to the message
In addition, there are outside influences that affect the effectiveness of the message. These include the environment in which the information is transmitted, the context in which it is conveyed, and the amount of interference present when the message is transmitted and received.
Interference is anything that blocks or changes the intended meaning of the message. Before a message can be transmitted, the sender must analyze the information at hand, and before the message can be processed, the receiver must interpret the information received. Interpretations of meaning are always subjective, based on one’s background and experience and preconceived notions that effect their worldviews. Therefore, communication is complex and forever changing, as meaning is molded during the process of transmission.
