Communication is so important in our lives. Besides satisfying social needs: involvement with others, control over environment, and giving and receiving affection. It also can be a link to physical health because researchers have demonstrated that a lack of close relationships can affect a wide range of health threats.
             On the other hand, in our childhood, we learn about our identity via the messages sent by others, and as adults our self-concept is shaped and defined through social interaction.
             Not every one needs the same amount of contact, and quality of communication. The point is that personal communication is essential for our well being.
             In the process of communication they're two types of model: the linear and the transactional model. In the linear model, the communication is introduced by a sender who encodes ideas and feelings into some sort messages and they conveys them by means of a channel into a receiver, who decodes the message.
             The transactional communications reveals that we usually encode, send, and decode messages simultaneously and not in one direction manner suggested by the linear.
             In this subject we concluded that communication is a transactional process in which participants create a relationship by simultaneously sending and receiving messages, which are sometimes distorted by noises.
             Within this chapter we also saw the principles and misconceptions that define what communication is.
             Communication can be intentional or unintentional. Intentional when you plan the words that you're going to say to someone. And unintentional when you have slip of tongue or send non-verbal messages to say something that you don't want to say.
             It's impossible not to communicate. We are always sending messages to other around us using verbal or non-verbal messages.
             Communication is irreversible. Words and deeds done are irretrievable
