Discuss how people navigated and communicated before the evolution of digital communication systems. What are the advantages of digital communication systems?

The answer to this question is given below in the explanation section.

Explanation:

Before the digital communication system, early human makes communication through signs and gestures and send messages to others by a number of different methods. They could send their messages through signals with fire and smoke, drums, or whistles. The early method of communication had two limitations: first, they were restricted by the time in which communication took place. Second, they were restricted by a place that could be used only between people more or less close to each other.

They navigate through signals and signs, for navigation they search for footprint, smoke, etc to search the populated area.  The compass is the old measure they used for navigation. They travel through horses and other means of traveling they mostly use animals in their traveling for convenience. As people get advances, they used other means of sending messages to each other through letters, then the telegraph took place and telephone.

Beginning with digital communication, such as sending emails, letters, video, and audio chat make the world shrink in the global village.

People now communicate with each other in half of second with each other using new means of communication such as "s k y p e", "what s app", etc.

Now with the use of digital communication, the distance gets shrink among people. One can talk while one setting at a different corner of the world to another corner of the world in seconds. Digital communication made life simple and easy.

People can navigate through new means easily such as using "goo gl e map" etc.
