History of Communication

At the beginning of life on earth, communication is used to express the needs of organic. Chemical signals in the early organisms used for reproduction. Along with the evolution of life, the chemical signals used in the primitive communication also evolved and opened the possibility of more complex behaviors such as mating dance in the fish.
In animals, in addition to sex, communication is also done to demonstrate the benefits, usually with an attack. Munurut evolutionary history of about 250 million years ago the emergence of "reptile brain" is important because the brain enables the physiological reactions to events in the outside world that we know as emotions. In modern humans, the reptilian brain is still present in the human brain's limbic system, and only the brain is covered by other "high level".

Humans communicate to share knowledge and experience. The general form of human communication signals, including language, speaking, writing, movement, and broadcasting. Communication can be interactive, transactive, aims, or no purpose.

Through communication, attitudes and feelings of a person or group of people can be understood by other parties. However, communication will only be effective if the message can be interpreted as the recipient of the message.

Although communication has been studied for a long time and are "antiques", has become an important topic, especially in the 20th century due to the growth of communication described as "a revolutionary discovery", this is because the increase of rapid communication technologies like radio. Television, telephone, satellite and commuter networks as industiralisasi big business and global politics. Communication in the academy may have their own department where communication is divided into time communication, communication for the host, publicist and others, but the subject will remain. Jobs in communications reflect the diversity of communication itself. Looking for the best communication theory would not be useful because communication is the activity that more than one event. Each of the theories and processes considered from a different point of view which they refer separately from their own perspective.

  Components of communication

Communication components are things that must exist so that communication can take place properly. According to Laswell communication components are:

     * The sender or communicator (sender) is the party that sends a message to other parties.
     * Message (message) is the content or purpose to be conveyed by one party to another party.
     * Channel (channel) is a medium where the message conveyed to the communicant. in inter-personal communication (face to face) can channel the flow of air vibration tone / voice.
     * Recipient or komunikate (receiver) is the party that receives messages from other parties
     * Feedback (feedback) is the response from the reception of messages over the content of the message.
     * Rules are agreed upon by the principals of communication about how communication will be run ( "Protocol")

    2. Communicant (receiver) giving feedback (feedback) or a response to the message sent to him, whether he understood or understand the message intended by the sender.

Communication Technology

In telecommunications, radio communications two-way through the first Atlantic occurred on July 25, 1920.

With growing technology, communication protocols were also developed, for example, Thomas Edison had discovered that "hello" is the greeting of the least berambiguasi via voice from a distance; other remarks such as hail can easily lost or distorted in transmission.

Limitations in the communication

Limitations in communication include:

    1. Language
    2. Time delay
    3. Politics
