Like the physical universe, the digital universe is large – by 2020 containing nearly as many digital bits as there are stars in the universe. It is doubling in size every two years, and by 2020 the digital universe – the data we create and copy annually – will reach 44 zettabytes, or 44 trillion gigabytes.
Between 2013 and 2020 the division of the digital universe between mature and emerging markets ( e.g., China ) will switch – from 60% accounted for by mature markets to 60% of the data in the digital universe coming from emerging markets.| 欢迎光临 SAS中文论坛 (http://www.mysas.net/forum/) | Powered by Discuz!
