What is Big Data, Anyway?
Imagine a spreadsheet so massive it crashes your computer just trying to open it. That's getting close to the scale of big data. It's not just about size, though. Big data is characterized by:
- Volume: We're talking about truly enormous datasets, often measured in petabytes or even exabytes.
- Velocity: Data is constantly flowing in from countless sources at incredible speeds.
- Variety: Big data isn't just numbers in rows and columns. It includes text, images, videos, sensor data, and much more.
Think about the sheer amount of information generated every minute on social media, by online purchases, or even by your smartphone's sensors. That's big data in action.
