The communication is the process that connects the readers of the book to the story told by the author. The communication is the process that connects the watchers of the broadcast to the events of the day. The communication is the process that connects my sister and I via the announcement of her wedding. True, the book, the tape and the invitation are a part of the communication process, but they are only a part. There are additional observations to be drawn from these examples.
Communication always happens between or among - it takes at least two to communicate.
Communication involves an exchange - of electrical signals, of sounds, words, pages of print, or whatever. Notice, for example, that each of the previous set of examples contained sender and a receiver and a message. The book was written by its author to be read by its audience. The video tape was produced by one group of people to be watched by another. And the invitation is a message sent from my sister to me.
