If we talk about data, then it is lovely. We keep it safe, on many hard drives or on our mobile phones so that it can be used when needed and this important data is not lost from us. This is only about data, because big data is very different from this. Earlier computer systems used to have very little hard drive memory, about 4 or 5 GB of memory.But today we see that 1TB, 2TB or 4TB hard drives have started coming into the computer system. Talking about mobile phones, the size of memory has increased in that too. It also uses micro HD card and very amazing Internet access. Whereas there was nothing like this before.
If we talk about big data, then there is nothing in front of it. If we talk about generating data for all of us in one day, then it is 3 to 4 hexabyte data. Together we generate so much data in just one day. hexabyte means approximately 3 to 4 million terabyte. This type of data is named Big Data.Here, data is collected in different forms in different ways. generate is also done and processed later. So that we can provide better service to all of us, big companies benefit. Normally, if we talk about data, then we cannot analyze it, when talking about big data, then it contains a lot of data which needs to be analyzed for the specialized hardware, specialized softwares. So that by using it we can normalize that data to get some meaning for ourselves.
If we talk about where big data comes from? What do we do that generates data? So this is all about our whole day's work, like talking about Facebook, in which post you commented, liked it, what photo was uploaded on it, what did you search from the net, even different big data in different sectors. What happens is, like the railways, a big company, the weather station data or the hospital's updates to the patient, how much he is recovering, all this data is getting generated every day.
There is so much data that it cannot even be fully processed, if it is separated, it will be a big thing. It also has many examples. Just like there is a company and they have to start their branch in a different country, if that company knows beforehand what the people of that country are saying about that company or about the company's products, what? Posting about that company in the Internet, what kind of feedback are you giving.If this type of analysis is done, then this information can be found whether it would be beneficial to start a company branch in that country.
If we talk about its privacy now, there is no privacy in normal internet but big data, which is very much, does not contain individual data. If you go and try to get your information only, then only the data related to that topic will be visible to you. It is very difficult to process and if a company says to process it then it is necessary to take care of 3 things, which is the volume of big data, so that it can be known how much data is being generated. Second, the velocity of data, the rate at which data is generated. And third, the variability of data, which variability of data is being generated. After this, big data can be analyzed with the help of different types of software, hardware. So that the company can get all the information. The amount of Big Data has become very high. Which is difficult to analyze.
