nowadays,people can communicate with others by using the cell phone and the internet,while in 30 years ago,mails and communal phones are in the dominant position.with the development of the society and the rapid increment of social value,it brought a lot great advantages.
in the first place,it is much more convenient for people around the world.it made things more personal and private.with the cell phone,we can talk to others in a secret way without let any other people overhear what is going on.
secondly,it enormously increase the amount of information that we impart to others.we can put lots of things in key board or have a long talk to others by the cell phone,which seems impossible for both the mails and communal phones.because there are always lots of people wait to use the phone,so people often had a time restriction,which means there is no right to stick up with the phone for a lnog time; and for mails,we all know it is often harder to write than to speak it up,so the information is also sadly little compared to cells and internet.
