Modern humans, nearly every day dealing with digital data. We use it and save it every day. Starting from a phone number that we store in HP, the movies on the hard drive, or foto2 that we upload on facebook. Books? The book had now been changed format, publishing Formerly synonymous with paper, and expensive! but have now we can publish our own books in digital format, and can be sold (or distributed free). www.virtualxbook.com one example.
But anyway, have we asked about this digital data, about how big that digital data around the world? it is stored, and the things associated with it?
Let's look at the following
NUMBER OF DIGITAL DATA WORLDWIDE
How big is the World Wide Data?
Twenty years of research, published in the journal Science this year calculate the amount of data stored all over the world from 1986 to 2007. In 2007 they estimate that there are about 295 exabytes of data that is stored around the world. If you do not know 295 exabytes, then it is at 295 billion gigabytes (295 billion GB) = X rata2 1,200.000.000.000 hard drive capacity today.
"Suppose we put such data in the form of a book and laid out, then it is able to cover the entire territory of the United States, or China in thirteen piles of books."-Dr. Hillbert Martin, University of Southern California in the BBC Science in Action-
Again, this data in 2007. And keep in mind that storage capacity doubles every three years. Multiplied by two, then around the world this year is estimated to save about 600 exabytes of data.
This means data2 on the hard disk drive + Quote all flashdisk2 + + SD Card + CD + DVD recording camcorders, etc. all over the world if you add up the total is plus minus 600 exabytes
HOW IS ALL STORED?
Most of the conversion from analog to digital is done in the last 2 decades. In 2002 the amount of digital data has exceeded analog. Usually data in the form of data storage technology are already in digital format since the early 2000's, and 94% of all digital data now stored in the last few years ...
In a pie chart can be seen, the composition of storage media ...
52% - HARD DISK. (as the laptop / PC net now)
28% - Optics. (CD, DVD, etc.)
11% - Digital Tape
9% - Other (including SD, flash, etc.)
Glancing 10 THROUGHOUT THE WORLD LARGEST DATA CENTER
campus, company, bank, website, facebook, google, they all certainly have a place specifically for the storage of data according to their needs.
top 10 data center:
above data are sorted based on the WIDER data center. Size in square foot (square feet) instead of square meters.
We can see from the table that the largest is 350 East CERMAX.
With extensive data center at 1.1 Million Square Feet. 102,193.344 square meters equivalent. If the area of our football field is 7140 square meters, then this means that extensive data center 350 East 14th CERMAX comparable to our football field wide. Wew!
