The infographic below from Cisco depicts the enormous growth of data on the
Internet. Be aware that the graphic is quite large. The Cisco blog says:
A zettabyte is roughly 1000 exabytes. To place that amount of volume in more
practical terms, an exabyte alone has the capacity to hold over 36,000
years worth of HD quality video…or stream the entire Netflix catalog more
than 3,000 times. A zettabyte is equivalent to about 250 billion DVDs.
By 2015, the majority of global Internet traffic (61 percent) will be in
some form of video—Internet video-to-PC, Internet video-to-TV, mobile video
, et al.The “dawn of the Zettabyte era” will be an unprecedented online
milestone that will occur in our lifetime.
To better understand the significance of a zettabyte, we have put together
an in-depth infographic to provide a visual snapshot of our online future.
The way the world uses the web is changing and this infographic provides a
quick Cisco perspective of what’s to come. |
