Communication is the exchange and flow of information and ideas from one person to another; it involves a sender transmitting an idea, information, or feeling to a receiver.

Communication technologies play as big a part in our private lives as they do in commerce and control in society. 

·  Geographic distances are no longer barriers to relationships thanks to the bridging power of communication technologies. 

·  We can also be entertained and informed in ways that were unimaginable a century ago thanks to these technologies and they continue to evolve and change before our eyes.

·  As this book goes to press in mid-2008, Google is the most valuable media company in the world in terms of market capitalization (the total value of all shares of stock held in the company). To understand how Google attained that lofty position, we have to go back to the late 1990s, when commercial applications of the Internet were taking off. 

·  There was no question in the minds of engineers and futurists that the Internet was going to revolutionize the delivery of information, entertainment, and commerce. 

*The technology's improvement create a better communication around the world following different levels of protocols.
