Question

How do companies like Google & Facebook keep up with all the data storage space their users need. Is it just a matter of permanently adding servers all the time.

Answer

Chris - We're all nodding our heads here. Yup, that's basically it!

Dave - The difficult bit is connecting them all together in such a way that if one of them dies it all carries on as if nothing happened. Chris - And I think it's worth re-iterating the words of Professor Andy Hopper from Cambridge University Computer Sciences who was in this studio a little while back. His stat was that the internet produces almost as much CO2 as the airline industry around the world. That's just data centres running to supply us with all the data that we are demanding.
