Communication is an intricate part of life. There are two types of communication.

• Verbal communication
• Non verbal communication

Verbal Communication
Verbal communication is recognized as a clearer form of communication than non-verbal communication, despite the overlooked forms of interference (background noises, strobes of light). However, all methods of communication are based on a linear model:

1) The act begins with a sender and a receiver;
2) the sender decides what message to send;
3) the brain encodes the message into the form of expression;
4) the message gets transmitted;
5) the receiver accepts the message; and finally
6) the receiver decodes the message.

Non Verbal Communication
All forms of life exchange ideas, even single-celled organisms transmit a chemical signal to interact with other organisms. This is an example of non-verbal communication. Every time you smile, frown or wince you send a message to someone else without uttering a word. Other forms of non-verbal communication are smoke signals, ritual dances, hand gestures/sign language and motions with light (lighthouses, spotlights, neon lights), which indicate that the transfer of a notion does not have to be physical. Music and art fit this description as well; through a composer’s speed and sound of melody and an artist’s use of colors and shapes, one can decipher a hidden message.

Evolution of Communication
The use of complex language began about 40,000 years ago with the Cro-Magnon man. Once language had been established, the next step was to record communication. One of the most well-known forms consisted of Egyptian’s hieroglyphics and depictions on papyrus made from reed writing tools and specialized ink. As the human race progressed, religious monks and wealthy nobleman were the only ones taught how to read and write while the rest of society relied on getting information via word of mouth. The monks would devote their time to copying versions of the bible by hand as part of their daily routine until 1445 when Johannes Guttenberg allowed for the mass production of text and images with his invention of the movable type printing press. His creation changed the way books were produced and gave way to the printing of newspapers and magazines.
