Computer graphic of global internet traffic

Internet traffic. Computer graphic of global internet traffic. Each line represents the path of sample data sent out to one of 20, 000 pre- selected locations using a system called Skitter. The lines are colour-coded to show the nationality of that part of the internet, for example: USA (pink), UK (dark blue), Italy (light blue), Sweden (light green) and white (unknown). The internet is a global computer network through which information can be shared. Maps like this will make moving around the internet easier, as well as showing when and where data jams occur.
