Communication involves the exchange of information through various channels between a sender and receiver. It can be intentional or unintentional and takes different forms depending on the context. There are six common frames of reference that shape communication including psychological, cultural, social, spatial, temporal, and historical biases. The basic elements of the communication process are the sender, receiver, message, channels, feedback, noise, and setting. Communication occurs on different levels from intrapersonal communication within ourselves to interpersonal communication between two people to larger forms like intercultural, interviewing, small group, and mass communication.
