Incredible Numbers： How much data can the Internet generate every day？

　　Focus on cutting-edge scientific and technological innovation and upgrading of traditional industries

　　With the popularity of the Internet, sensors and various digital terminal devices, an interconnected world is taking shape. At the same time, with the explosive exponential growth of data, digitalization has become the basic force to build a modern society, and it has pushed us towards an era of deep change.

　　So, how much data can our world produce every day in this new era of surging digital torrent?

　　In order to have a general idea of the data units in the following content, we can learn about each data unit first.

　　1B (Byte byte) =8b (bit bit)

　　1KB (Kilobyte kilobyte) =1024B.

　　1MB (Megabyte "megabyte" for short) =1024KB.

　　1GB (Gigabyte is also called "gigabit") =1024MB.

　　1TB (Trillionbyte terabyte) =1024GB

　　1PB(Petabyte petabyte) =1024TB.

　　1EB(Exabyte billion bytes) =1024PB.

　　1ZB (Zettabyte ten trillion bytes) =1024EB.

　　1YB (Yottabyte billion bytes Yao bytes) =1024ZB.

　　Whether it is email sending, video uploading, daily online search, or even daily data collection of self-driving cars, we will find that the amount of data formed in the Internet age is incredible.

　　In 2025, the amount of data generated worldwide will reach 491EB every day.

　　According to the report "Data Age 2025" released by IDC, the annual data generated in the world will increase from 33ZB in 2018 to 175ZB, which is equivalent to 491EB of data generated every day.

　　So how big is the data of 175ZB? 1ZB is equivalent to 1.1 trillion GB. If all 175ZB are stored in DVD, the height of DVD stack will be 23 times that of the Earth and distance to the moon (the nearest distance between the Moon and the Earth is about 393,000 kilometers), or it will circle the Earth 222 times (one circle is about 40,000 kilometers). At present, the average Internet speed in the United States is 25Mb/ s, and it will take 1.8 billion years for a person to download the 175ZB data.

　　With the popularity of Internet of Things infrastructure, smart phones and wearable devices, each of us is generating a lot of data all the time. We have also completely become digital individuals.

　　According to IDC’s forecast, in 2025, every connected person in the world will have an average of 4,909 data interactions every day, more than eight times that of 2015, which is equivalent to generating one data interaction every 18 seconds.

　　In 2019, the world sent and received 293.6 billion emails every day.

　　E-mail is one of the important channels for users to obtain information daily, especially for enterprise users.

　　According to the statistics of Radicati Group, the number of global e-mail users reached 3.8 billion in 2018, that is, more than half of the global population used e-mail.

　　In 2018, the total number of commercial and consumer e-mails sent and received worldwide exceeded 281.1 billion. It is estimated that the number of e-mails per day will reach 293.6 billion in 2019 and 333.2 billion by the end of 2022.

　　Interestingly, even though the total number of e-mails has been increasing, the growth rate has been decreasing year by year. There is obviously the influence of social media and more convenient mobile communication.

　　A connected car will generate 4TB of data every day.

　　According to Intel’s prediction, in 2020, a networked self-driving car will generate 4TB of data every 8 hours. This mainly comes from the hundreds of on-board sensors that self-driving cars will have. Intel said that only the camera can generate 20-40Mb of data per second, while the lidar will generate 10-70MB of data per second.

　　Brian Krzanich, CEO of Intel Corporation, said that in 2020, Internet users will generate 1.5GB of data every day. Based on this calculation, each connected car driving on the road will generate about 3,000 people’s data. And 1 million self-driving cars will generate 3 billion people’s data.

　　In 2025, the global Internet of Things connected devices will reach 75.44 billion.

　　The ubiquitous Internet of Things devices are turning the world into a "digital earth". According to HIS data, by 2025, the total installed capacity of Internet of Things (IoT) connected devices in the world is expected to reach 75.44 billion, about five times that of 2015.

　　Wearable devices are an important part of all kinds of networked devices. It is predicted that by 2020, global wearable devices will generate 28PB of data.

　　There are 5 billion online searches every day in the world.

　　In the Internet age, search engines have become an important channel for people to find daily solutions. It has become the normal state of work and life to search if you have something to do. Especially with the popularity of smart phones, we are generating search data anytime and anywhere.

　　According to Smart insight, there are currently 5 billion searches every day in the world, of which 3.5 billion are from Google, accounting for 70% of the global search volume, which is equivalent to processing more than 40,000 searches per second. Back in 2000, at that time, Google searched only 14 billion times a year.

　　Ubiquitous social data

　　Smartphones make people’s social life completely digital, spend more and more time on social networks every day, and the amount of data generated is correspondingly increasing.

　　According to Facebook statistics, Facebook generates 4PB of data every day, including 10 billion messages, 350 million photos and 100 million hours of video browsing. In addition, on Instagram, users share 95 million photos and videos every day; Twitter users send 500 million messages every day.
