In his guest lecture Prof. Cox told us that 2 billion photos were
uploaded to Facebook each day. This website/blog:
http://andylark.blogs.com/andylark/2009/12/amazing-facebook-stats.html, claims that 2.5 billion photos are uploaded each month (as of Dec 2, 2009). This is roughly 83 million photos/day. If each photo averages one Megabyte (one million bytes) then there are 83 million Megabytes uploaded each day. How many terabytes is this? Note that a Gigabyte is a billion bytes and a Terabyte is a trillion bytes (roughly). A billion is a thousand million and a trillion is a thousand billion. |
