What is Big Data? Characteristics, Tools, Types, Internet of Things (IOT)
What is big data?
With technology making an inroad into almost every sphere of our lives, data is being produced at a colossal rate. Today, there are over a billion Internet users, and a majority of the world’s web traffic is coming from smartphones.
At the current pace, around 2.5 quintillion bytes of data are created each day, and the pace is increasing with the continuous evolution of the Internet of Things (IoT).
This results in the generation of data sets of enormous volume and complexity called Big Data.
Characteristics of Big Data
These are following five characteristics of big data which discussed below:
Volume
The most The exponential growth in the data storage as the data is now more than text data. The data can be found in the format of videos, music, and large images on our social media channels.
It is very common to have Terabytes and Petabytes of the storage system for enterprises.
Velocity
The data growth and social media explosion have changed how we look at the data. There was a time when we used to believe that data of yesterday is recent.
As a matter of fact, newspapers are still following that logic. However, news channels and radios have changed how fast we receive the news.
Variety
It asserts that Data can be stored in multiple formats. For example, database, excel, CSV, access, or as the matter of fact, it can be stored in a simple text file. Sometimes the data is not even in the traditional format as we assume, it may be in the form of video, SMS, pdf, or something we might have not thought about it.
Veracity
Big data can be sometimes inconsistent, biased, noisy or there can be abnormalities in the data or issues with the data collection methods. Veracity refers to the trustworthiness of the data because processing such incorrect data can give wrong results or mislead the interpretations.
Value
Big data is not only just a big pile of data but also possesses to have hidden patterns and useful knowledge which can be of high business value.
But as there is a cost of investment of resources in processing big data, we should make a preliminary inquiry to see the potential of the big data in terms of value discovery or else our efforts could be in vain.
Big Data Tools
These are some big data tools mentioned below:
