How We Store Data Till Now ?
Humans are producing data rapidly at an unimaginable rate , to the point that storage technologies can't keep up.
Present day technologies we used to store data are-
1) Hard drive or Hard disc
2) Flash drive / Pen drive
3) CDs/DVDs
4) Cloud Computing
Now slowly the usage of flash drive , CDs & DVDs are getting over , after the introduction of cloud computing
What Is Cloud Computing?
Cloud computing is nothing but the practice of using a network of remote servers hosted on the internet to store manage and process data , rather than a local server or personal computer in simple words we may say that if someone is connected through a network and stored a data from one computer he/she can access the data from another computer by the help of network , without the use of flash drive, CDs and DVDs .
Present Day Challenges.
According to some statistics each day around 2.5 quantillion bytes of data is created , by 3.7 billion humans who now use the internet . Due to the facilities of the cloud computing we don't delete anymore , nor do companies , especially the value based data . As a result we might run out of data storage .
Misconceptions Or Myths Of Cloud Storage.
What we think about cloud storage is infinite storage capacity of data, but cloud storage is just someone else's computer . Most people don't realise it .
Is DNA The Solution For Better Data Storage?
The idea of storing digital data in DNA is several decades old, but recent work from Harvard and EBI(European Bioinformatics Institute) showed that progress in moderns DNA manipulation methods could make it both possible and practical today . Many research groups , including at ETH Zurich, the University of Illinois at Urbana Champaign and Columbia University are working on this issue. The University of Washington and Microsoft holds the world record for the amount of data successfully stored in and retrieved from DNA is 200 Mb(megabytes).
How Storage In DNA Is Different From The Traditional Data Storage?
Traditional media like hard drives, DVDs store digital data by changing either the magnetic, electrical or optical properties of a material to store. To store data in DNA, the concept is the same, but the process is different . DNA molecules are consist of nucleotide- adenine guanine,cytosine, thymine, usually denoted as A,G,C and T
Challenges Which Are Still Remaining
1) At present , DNA storage is experimental . Before it launches globally,it needs to be completely automated.
2) The processes of storing and reading the data must be improved , the are relatively slow.
