Since the dawn of time, communication has played a pivotal role in advance of every great civilization. It has been a constant endeavor to convey things in a fast and secure manner in the absence of which, great empires have just succumbed to crisis. There is an old saying that highlights the feat that a little miscommunication achieved, ‘For the want of a nail, a horseshoe was lost. For the want of a horseshoe, the steed was lost. For the want of a steed, the message was not delivered. For the want of that undelivered message, the war was lost.’ The means to transport and deliver messages have evolved ever since.
