DNA Data Storage:-Whole Internet in a glass of water


DNA Data storage has become a hot topic these days. It is the revolutionary technology that can store the whole internet in just a glass of water. So let's decode how does this technology works and how can it store the whole internet in a glass water.

 What is DNA Data storage?
DNA digital data storage is defined as the process of encoding and decoding binary data to and from synthesized DNA strands. DNA molecules are genetic blueprints for living cells and organisms.
How does DNA Digital Data Storage Work?
DNA basically is used to recover characteristics of dinosaurs even today. What if we can store our data in DNA so that we are able to store our data and preserve our data for many years. So let's start from understanding the basics of DNA.DNA stands for DeoxyriboNucleic Acid. So in a DNA, we have four nucleotides in the sequence of ATGC((A) Adenine (T)Thymine  (G)Guanine (C) Cytosine

 Using these nucleotides we code the data, for example, we will code A as 1, T as 2, C as 3, G as 4 and so on. We compress the data code by using the lossless Huffman Coding Technique so that it is easy for us to store data on DNA. 

 An Artifical DNA sample is created using a DNA synthesizer which creates the base DNA where the data is coded using the ATCG sequence. After the data is coded the DNA can be stored for many years and also does not require electric supply. To restore the data we use a DNA sampler which decodes the data that has been stored in the form of DNA and we are able to access after processing.
How can we store the whole internet in a glass of water?
According to the experiment that was conducted in 2016 we will be able to store about 
1 exabyte(10000000000GB/MM3) of data in a 1mm³ of DNA.If we talk about 1cm3 
of DNA then we are able to store about 1 Zettabyte (1 trillion GB) of Data. According to a study the whole internet requires 15 Zettabyte of space to be stored. So if we store the data from the internet in DNA data storage technique it will require us just 15cm3 of space which is equal to the amount of space in a normal glass of water. According to the research we require 1KG of DNA to store all the information and Data that is present in the whole world(offline & Online Combined)

Is DNA Data Storage Really Possible?
Scientists have been working on DNA data storage for many years. Successful test and experiments have been conducted in 2017 when Scientists were able to store data and easily recover from DNA. Let's hope that it turns into a reality where we will be able to store tons of data in a small space.

 Disadvantages of DNA Data Storage
Cost:-The cost of storing and recovering the data from DNA is very high and cannot be used for day to day purposes 

 Speed:-The amount of time that we require to access the data is very high. And it takes a significant amount of time to encode the data on to the DNA.

151 MP Camera :-Dope Tech Explained

A 151 MP Camera is something that we could  not imagine a few years ago.But this is made possible thanks to the company"PhaseOne".The PhaseOne XF IQ4 captures ridiculous amounts of deatail. So let's have a look at this Dope Tech. Phase One Camera Specifications Many of the medium frame cameras that try to capture photos above 100 mp use the technique of capturing multiple shots to up the megapixel game rather actually increasing the size of the sensor.PhaseOne however has turned up the camera sensor megapixel game with a staggering 151mp camera sensor that is backside illuminated The camera muster an ISO 50 to 25,600 sensitivity despite the extreme resolution, and you can use both timelapse and bracketing tools independently of the main camera body. The IQ4 also scratches the itch for pro photographers with XQD and SD card slots as well as tethering through Ethernet, USB-C or wireless. If it sounds ridiculously expensive... well, it is. The regula...

Thunderbolt 3 Explained

  The ports on the side of your laptop are important. They decide what you can do on your device and how quickly you can do it. When Apple introduced the first version of the new style MacBook Pro, Apple ditched every single port on its old machines and replaced it with just Thunderbolt 3.Many PCs have now followed suit into the world of Thunderbolt - although it's still relatively few that have gone the whole hog and dumped all other ports the same way that Apple has on the Pro and MacBook Air. So in this article let's understand what's Thunderbolt 3? What is Thunderbolt 3? Thunderbolt 3 is the latest version of Thunderbolt, and it uses the same design as the familiar USB-C connector. This connector is used for simplicity Intel introduced the Thunderbolt platform in 2011 at a time when USB 3.0 was all the rage and could transfer data at speeds up to 5Gbps. Thunderbolt was capable of twice that, plus it could transfer multiple types of data, not just serial data to storage ...

QR Codes Explained

We use QR codes daily for different things like making payments, storing your travel information, visiting websites, connecting to Wi-Fi networks. These barcodes can be captured using smartphones. So in this article let's understand what is a QR code and how do they work. What is QR Code? Qr codes were first developed by a subsidiary of Toyota 'Denso Wave' to quickly track vehicles and parts through the company's automotive manufacturing process.QR code stands for Quick Response Code. Although Denso Wave still holds patents over the technology, QR codes are free for anyone to use without a license fee as long as the intellectual property is being used within the defined ISO/JIS standards.QR codes are machine-readable labels — computers can understand them much more easily than they can understand the text. In 2016 for instance, Snapchat and iMessage introduced support for QR codes as a method of adding new friends, WhatsApp uses QR codes as a quick way to access the de...
