People use internet to get different kinds of information they need. We sit in different social networks like Instagram, Facebook or Twitter to see how our friends, relatives or just famous people live. We watch various kinds of videos and download movies, music, pictures we want to see or listen to. We also read different interesting electronic books from Internet and play games that work only with Internet such as Clash of Clans or Clash Royal. In one word, Internet is everything and all sources of our world are in Internet.
