The amount of data on the Internet now is 1 Zettabyes or 1,180,591,620,717,411,303,424 bytes. If all all that data was put into books and piled up it would reach the Sun.

If you laid out all the DNA strings in your body it would stretch for 12 million miles.

And one you really wanted to know: If you watch television for one hour the world population will have eaten 7,092 tons of Bananas.
 
Well, one amazing statistic is that one zettabyte (without an "s" as there is only one of them) is 1,000,000,000,000,000,000,000 bytes or 10exp21 bytes.

Which, as all decimal multiples tend to be, is composed of a number one and a string of zeros. Not a string of random digits like your number - dunno what that is but its statistically quite different from a zettabyte.

Would it though? Surely if you printed that many books the mass of the earth would increase so much that it would depart its current orbit. And we'd have to cut all the banana trees down to make the paper, so nobody would be able to eat bananas any more. Also, this big pile of books flailing around would smash all the geostationary satellites so there would be no more television. Your theorem sounds like a load of bosh to me.

Well yes and no.

The SI prefix zeta denotes the base unit raised to 10^21. So one zetametre is 10^21 metres.

However, the byte is not an SI unit. As data is all binary bits, tradition has meant that bytes are measured in powers of 2. It so happens that 2^10 is 1,024 - which is pretty close to 1,000 and so the term kilobyte was used. This is the basis for sizing memory chips, hard drives and the data your mobile phone uses. But that pesky 24 at the end means things snowball quite quickly. So a megabyte is 1,048,576 bytes (2^20). And indeed 2^70 is equal to 1.18059 x 10^21. It's 2^70 for zeta byte as 21 = 7 x 3 -> 2^10^7.

It comes down to different applications of the term - whether one is dealing with SI units or something else, where usage and habit have changed its application.
 
Say wot ?

Clearly this dark corner of the universe must have an anorak rather than an ensign as the distinguishing feature.
Not sure who to feel most sorry for.
The mathematician who does not understand the byte, or the other one who felt he had to show off by explaining it. Please God that you do not ever get to breed, especially together.

And the nautical relevance of any of this?

A Zettabyte isn't all zeros, here are all the numbers:
1 Bit = 1/8 Byte
1 Nibble = 1/2 Byte
1 Byte = 1 Byte
1 Kilobyte = 1,024 Bytes
1 Megabyte = 1,048,576 Bytes
1 Gigabyte = 1,073,741,824 Bytes
1 Terabyte = 1,099,511,627,776 Bytes
1 Petabyte = 1,125,899,906,842,624 Bytes
1 Exabyte = 1,152,921,504,606,846,976 Bytes
1 Zettabyte = 1,180,591,620,717,411,303,424 Bytes
1 Yottabyte = 1,208,925,819,614,629,174,706,176 Bytes
1 Brontobyte = 1,237,940,039,285,380,274,899,124,224 Bytes

And yes a pile of books reaching the sun would tilt the earth of it's axis but it was a good way of explaining just how big the pile would be.

+1 (x10^21)
