What is BIG DATA? And introducing the 3 (or 5) V's

The video tutorial explores the concept of big data, explaining its components, scientific notation, and data measurement in bits and bytes. It discusses data storage sizes, the human context of big numbers, and the growth of data creation and storage capabilities. Definitions of big data and the five Vs—variety, volume, velocity, variability, and veracity—are provided. The tutorial concludes with the challenges and implications of big data usage.

What are the three main components of Big Data?

• Storage, Analysis, Access

• Scale, Management, Technology
