Effective communication is a two-way process with defined elements like a sender, message, medium, receiver, and feedback. It can take verbal forms like oral language and written text or non-verbal forms like gestures, facial expressions, and proxemics. Maintaining open communication channels internally and externally is important for any organization or interpersonal relationship.
