- 6. Data: 6 From the beginning to 2005 of Human Era, Humans created 130 Exabytes of data
- 7. Data 7 Athis letter will takes a size of 1 byte A page of 1024 letters takes a size of 1kb A book of 500 pages takes a size of 500kb A library having 1000 books of size 500mb
- 8. Data 8 A human DNA takes a size of 1 Gb
- 9. Data 9 If we cut down all the trees in amazon rainforest and made paper from it and started filling data in it,it will generates around 1-2 petabytes of data
- 10. Data 10 If we further zoomed out it will make a data of 1000 petabytes
- 11. Data 11 1 petabyte is 1000000 of gb 1 Exabyte is 1000 petabytes 2005 - 130 exabytes 2010 - 1200 exabytes 2015 - 7900 exabytes 2020 - 40900 exabytes (source :www.wired.co.uk)
