Communication is a two-way process of exchanging meaning, facts, ideas, opinions, and information between a sender and receiver. The communication cycle involves a sender encoding a message, sending it through a channel, the receiver decoding the message, and potential feedback from the receiver to the sender. Communication has several objectives like providing information, taking action, building relationships, and solving problems. It benefits individuals, organizations, governments, and society as a whole. Communication can be classified as verbal/oral, written/non-verbal, formal/informal, internal/external, and different styles.
