The scale of the internet is jaw-dropping – and it’s only going to get bigger and bigger.

Just take a look at the infographic below and how many bytes of data are expected to be carried across the web by 2016. It’s a big number – so big that it’s got 21 zeros after the one.

That number is known as a zettabyte and is equivalent to 250 BILLION DVDs. Put it another way, you wold need one BILLION one terabyte hard drives to store that much information.


Recent excellent analysis by experts at Cisco underline just how big the network now is and that expansion will continue apace into the future.
