What is Data Explosion?
The world is currently used to sparing everything without exception in the electronic space. Processing power, RAM speeds and hard-disk sizes have expanded to level that has changed our viewpoint towards data and its storage. Would you be able to envision having 256 or 512 MB RAM in your PC now?
On the off chance that we comprehend idea of byte, we can envision how data growth has expanded over time and how storage systems handle it. We know that 1 byte is equivalent to 8 bits and these 8 bits can represent character or expression. An archive with huge number of bytes will contain huge number of characters, expressions and spaces etc. Similarly, megabyte (MB) is million bytes of information, gigabyte (GB) is billion bytes of information and terabyte (TB) is trillion bytes of information. We use these terms while managing data and storage, on our everyday activities.
But it doesn’t end here. Next comes the petabyte, which is quadrillion bytes or million gigabyte. Ones after that are Exabyte, Zettabyte, and Yottabyte. Yottabyte is basically trillion terabytes of information. There are considerably higher numbers and we’ll stop here now.
As indicated by report by Global Information Enterprise, IDC, in 2009 that aggregate sum of information in world was 800 EB. It is expected to ascend to 44 ZB before finish of 2020, i.e., 44 trillion gigabytes. Second explanation they made was that 11 ZB of this information will be put away in cloud.
The rapid or exponential increase in the amount of data that is generated and stored in the computing systems, that reaches level where data management becomes difficult, is called “Data Explosion”.
The key drivers of data growth are following :
- Increase in storage capacities.
- Cheaper storage.
- Increase in data processing capabilities by modern computing devices.
- Data generated and made available by different sectors.
