This unit discusses the scope and significance of business communication. It defines communication as a two-way process of sharing information between a sender and receiver. Communication can be verbal, including oral and written communication, or non-verbal through body language. Effective communication skills are important for individuals and organizations. The communication process involves a sender encoding a message, transmitting it through a medium, the receiver decoding it, and providing feedback to complete the process. Audience involvement and controlling the stage are also discussed as important aspects of presentations.
