Communication is the process of exchanging information between two or more members for whom the information is meaningful so that the exchange becomes meaningful as an act. We communicate for example between living beings by exchanging thoughts, messages, feelings or information through speech, image, writing, behavior or between humans and intelligent machines. To carry out the communication process, a transmitter, a receiver, and a common code are used, e.g. musical, linguistic, gestural, traffic, audio, visual, color, etc.There are four types of communication: verbal, non-verbal, visual and written communication. No matter how we communicate, start by thinking about what the reader/listener should think, feel and do once they’ve heard or read our message.
