what is small world phenomenon related to networks?

Answer 1

Perhaps you are referring to how computer networking (the Internet in particular) makes it a "small world"? Another way to say it is that technology and the Internet have made the world flat. It refers to "globalization" and the fact that networks and the Internet and technology have changed the way we live, work, shop and learn, not to mention the way we communicate and collaborate... just look at Y!Answers as an example. People now interact from halfway around the world as if they were sitting right next to each other. We can get dozens of answers to a question in SECONDS that our grandparents would have spent days or weeks researching in a library. It's as if we are all sitting in a virtual conference room regardless of how far apart we are geographically, I think that's the idea your asking about.
