Introduction
In the modern digital age, data is everywhere — from online shopping habits to social media posts and mobile app usage.
This explosion of data has given rise to a new concept called Big Data — massive, complex data sets that can’t be processed using traditional methods.
Big Data is transforming how businesses, governments, and societies function across the globe.
1. What Is Big Data?
Big Data refers to large volumes of structured and unstructured information generated every second.
It is characterized by the three Vs:
