Communication is the process of conveying and receiving information between individuals through verbal and nonverbal means. There are two types of communication: verbal, which includes speaking and writing, and nonverbal. The communication process involves a sender transmitting a message to a receiver, who then provides feedback. Business communication can be external, involving those outside the organization, or internal, which flows upward, laterally, or downward within a company. Barriers like language and culture can interfere with effective communication.
