Communication involves the transmission of information from a sender to a receiver. The communication process consists of several steps: a sender encodes a message and transmits it through a channel to the receiver. The receiver then decodes the message. Feedback is provided to complete the communication loop. Effective communication skills are important in interpersonal interactions, organizations, and governance at local, national, and international levels. Within organizations, communication allows for exchanging information, reaching agreements, and executing decisions. At different levels of governance, communication enables coordination, international treaties, and maintaining relations between organizations like the UN. Strong communication skills are essential for professional success in many fields today.
