2. Definition of Big Data: Big data refers to extremely large datasets that cannot be efficiently processed, analyzed, or stored with traditional data processing tools. It's characterized by the three Vs:

• Volume: The sheer amount of data.
• Velocity: The speed at which new data is generated and needs to be processed.
• Variety: The different types of data (structured, unstructured, and semi-structured).
