DATA GENERATED EACH DAY

Data generated each day

We currently deal data with kilobytes, megabytes, gigabytes, or even terabytes . These data units are common everyday amounts that the average person may run into. Units this size may be big enough to quantify the amount of data sent in an email attachment, or the data stored on a hard drive but just 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. In the coming years, however, these zettabytes / yottabyte will begin to seem more common  that’s because the entire digital universe is expected to reach 44 zettabytes by 2020. Going by this number means there would be 40 times more bytes than there are stars in the observable universe.

A Sneak peek of  Data

We are  well  acquainted with the following data scales in terms of units.

Abb. Unit Value Size (in bytes)

• b bit 0 or 1 1/8 of a byte
• B bytes 8 bits 1 byte
• KB kilobytes 1,000 bytes 1,000 bytes
• MB megabyte 1,000² bytes 1,000,000 bytes
• GB gigabyte 1,000³ bytes 1,000,000,000 bytes
• TB terabyte 1,000⁴ bytes 1,000,000,000,000 bytes
• PB petabyte 1,000⁵ bytes 1,000,000,000,000,000 bytes
• EB exabyte 1,000⁶ bytes 1,000,000,000,000,000,000 bytes
• ZB zettabyte 1,000⁷ bytes 1,000,000,000,000,000,000,000 bytes
• YB yottabyte 1,000⁸ bytes 1,000,000,000,000,000,000,000,000 bytes

The digital universe is growing 40% a year into the next decade, expanding to include not only the increasing number of people and enterprises doing everything online, but also all the “things” – smart devices – connected to the Internet, unleashing a new wave of opportunities for businesses and people around the world. Thus in the future we shall primarily deal with  zettabytes and  yottabytes!

A rough estimate of Data that is generated each Day

Some key daily statistics highlighted in the infographic:

500 million tweets are sent

294 billion emails are sent

4 petabytes of data are created on Facebook

4 terabytes of data are created from each connected car

65 billion messages are sent on WhatsApp

5 billion searches are made

By 2025, it’s estimated that 463 exabytes of data will be created each day globally – that’s the equivalent of 212,765,957 DVDs per day!
