There are several types of communication. Written communication avoids distortion of meaning and provides a permanent record, but oral communication allows for easy response and motivation. Non-verbal communication uses symbolic methods like gestures. Communication can also be classified by its method (visual, audiovisual), flow of information (downward, upward, horizontal), relationship to the organization (formal, informal), and function (organizational, routine, specialized, promotional). Overall, the types of communication provide different benefits depending on the situation and goals.
