Size of the net

How big is the internet if someone wanted to attempt the impossible and download it? I assume it grows all the time but at anyone time is there a way of predicting / calculating the rough size?

I don't think you are asking about the internet, but about data on viewable on the web.

If I'm correct, then I reckon you should look at Google where it says Searching 4,285,199,774 web pages and double the number there for the number of pages (since Google doesn't index them all). But of course that doesn't tell you how big those pages are :)
