What is IP Address?

According to the Google definition, IP Address is a unique string of numbers separated by periods that identifies each computer using the Internet Protocol to communicate over a network". Having an IP address defines your identity just like your street address or school ID number. I learn websites, such as Facebook, Youtube, Myspace, and so on, did not exist with in the last ten years.

My reaction for the "Mind Reading" video:

For the man who "mind read" other people, I knew some trickery in play. It did not occur to me that the power of social media was in play. I have seen this kind of video before when other people can track your information just by knowing your name and local location. Lesson be learned: Do not try to post everything going on in your life. You might attract more people than you would want outside your friends.
