The Independent: The fastest-ever network has been developed and demonstrated by a team of Danish researchers. They say the breakthrough could greatly improve the speed of the commercial internet.
The team from the Technical University of Denmark (DTU), says the record-breaking network can transfer more than five terabytes of data per second.
For comparison, the entire hard drive of a Mac Book Pro laptop is only half a terabyte. This means you could back up your computer's hard drive in the blink of an eye.
To download a movie (around 1GB) would take a fraction of a millisecond; you could theoretically download thousands in under a second.
