The internet allows people to communicate faster than ever and has become an important part of daily life in most developed countries. Without it, life seems to stop but not everyone has access to computers and the internet, for example: people in less developed countries or the older generation who have never had to use computers for school or work.
As technology improves, more devices to help us communicate are being developed. How we communicate is changing too and we talk less to people and text more. Some people in the communications industry believe that if given the choice of how to contact someone, more people are choosing their phone and not their computer. Phones are cheaper than computers and now have internet access and more functions than we know or have time to use. A separate camera or personal stereo is no longer necessary. Today's phones take pictures, play music, book flights and hotels, and much more. They come with additional applications which allow us to find out information very quickly. So, connecting with people through your phone is definitely more practical for this day and age. Modern mobile phones provide us with all that our computers do and more, at any time and
anywhere.
There are of course disadvantages too and anyone who has lost their phone will tell you how strange it feels. Some people are totally lost without them and feel they have no social life. But as society becomes more of a phone-culture, a lot more will change. The next time you go out, see how phones are changing our society, how we communicate and how we live. The world might be getting smaller but it might also be that we are forgetting how we used to talk to each other
