HISTORY OF COMMUNICATION

From early civilizations to today the ways in which we communicate have been improved by the advancements made by technology. Communication can be defined as the transmission of sound, written symbols (written language), and images. Today's instantaneous communication is made possible only because of the types of devices we use and the network systems that are in place to carry this information.

People have always communicated and one of the first methods fire. It provided a focal point so that early people could gather together, feel safe, and share stories. Later it was used as a means of signaling other groups over relatively long distances. The invention of the wheel has also improved how people communicate. It allowed people to carry messages more quickly over longer distances. A good example would be the early mail services that used horse and cart.

As you work through this assignment you will begin to understand the role that these and other inventions have contributed to the ways in which we communicate.
