#研究分享#【每天到底能产生多少数据?】你肯定听说过TB/GB/MB/KB,这些数据单位是普通人可能遇到的常见日常数量。但是再过几年,这些数据将会听起来很陈旧,因为到2020年整个数字世界预计将达到44个ZB。目前的关键信息统计可以包含:发送了5亿条推文、发送了2940亿封电子邮件、Facebook上创建了4 PB的数据、每个连接的汽车都会创建4 TB的数据、WhatsApp发送了650亿条消息、进行了50亿次搜索。伴随数据量的进一步增大,下一代的互联网会发生怎样的变化?http://www.looooker.com/?p=67740

You’ve probably heard of 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, for example.

In the coming years, however, these common units will begin to seem more quaint – that’s because the entire digital universe is expected to reach 44 zettabytes by 2020.

If this number is correct, it will mean there are 40 times more bytes than there are stars in the observable universe.

A Crash Course in Data

Today’s infographic comes to us from Raconteur, and it gives us a picture of this new data reality.

Before we get to how much data is created each day – both now, and in the future – it’s worth getting acquainted with how data scales in terms of units.

Abbreviation 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

There’s no doubt that data literacy will only become more important in the future, so make sure you know your zettabytes from your yottabytes!

A Day of Data

How much data is generated in a day – and what could this look like as we enter an even more data-driven future?

Here are 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!
