Forms of communication can be categorized into five main types:
1) Intrapersonal communication occurs within ourselves and involves thoughts and self-perception.
2) Interpersonal communication happens between two people through verbal and nonverbal exchange.
3) Group communication takes place when a small number of people meet to solve a problem.
4) Public communication involves one speaker conveying a message to a larger audience.
5) Mass/machine assisted communication uses technology to transmit messages to many recipients through media.
