Telephones before and after the revolution

Before and after the revolution

Before the revolution, people did not know the phones. They had to move and communicate each other face to face. For those who had family away from them, they had to make a long processus to send letters.

But, after the revolution, people were not forced to move or to send letters. They had the ability to communicate remotely without seeing, talking to someone on the other side of the world without tiring. But it was a little difficult for them. Phones, at this time were therefore wall so for a person receiving a call that is not at home, could not have any information. But these days, the phone has evolved so that we can move with and receive any calls on oneself. It is the evolution of technology.
