How Mobile Phones Work

First things first, let us start with a flashback.

Don’t worry, it won’t take a long time, we can return for dinner, say ‘Bye’ to your mom, dad and get ready.

Just ten years back, almost all the houses had some curious looking notebooks, which they called ‘telephone book’. People used it to note down names and phone numbers of their relatives, friends in perfect alphabetical order. Whenever they want to talk to somebody, all they need to do is, refer to this book and voila! They got the required phone number! But surprisingly, now we don’t find such notebooks anymore. What happened? How can they all vanish all of a sudden?

For the past many years, technical experts are predicting that our world is shrinking. Not physically, but each one of us are becoming connected to all others, making it a global village.

You might have seen science fiction stories, where machines take complete control of the world. When we read them, it looks like a very wild, funny imagination, to think of human beings becoming slaves of stupid machines.

But just look at what mobile phones are doing to us today. They have changed our lifestyles so much, as they determine at what time we should do what, who should talk to us and who shouldn’t - May be there is some truth in all those science fiction stories? Today, we assume a mobile phone is all we need to succeed in this world. Is there any truth in that belief? Growth of mobile phones and their impact is good for the society? Or bad? Are there any side effects which we are overlooking?
