Non-verbal communication means communicating without words. The person transmitting the message is called the sender. Communication aims to make people work together for the common good of an organization. Barriers during communication can hinder the process. Paralanguage describes all non-verbal forms of human communication. Communication is usually interpersonal, involving information transferred from one person to another. A channel connects the sender to the receiver. Distortion in word usage can be a barrier to effective communication.
