Communication is the process of exchanging information, usually via common system of symbols. It takes a wide variety of forms, from two people having a face-to-face conversation, to hand signals, to messages sent over global telecommunication networks. The process of communication is what allows us to interact with other people; without it, we would be unable to share knowledge or experiences with anything outside of ourselves. Common forms of communication include speaking, writing, gestures, and broadcasting.
