The digitalization of communication methods has changed the way we communicate. There was a time when you were greeted by the telephone operators first and it took almost a life to get a chance to talk to the person on the other side. But now, it is all about a few swipes on the screen and you are through. Mobile phones have not only changed the way we talk to the others, but these have also replaced the computers to carry out many day-to-day activities. These activities include entertainment, games, calculators, converters, and shopping to name a few.
