Communication involves the transmission of ideas, thoughts, and emotions from a sender to a receiver using various elements and channels. The communication process includes encoding a message using language, senses, and physiological elements by the sender, transmitting the message through a channel, decoding and understanding the received message by the receiver, and providing feedback. Both verbal communication through language and non-verbal communication through facial expressions, senses and emotions are learned skills that follow a process of encoding, decoding, and feedback between individuals.
