Big data

Definition

Big data refers to the vast volumes of structured and unstructured data that are generated at high velocity from various sources. This data is so large and complex that traditional data processing software cannot handle it effectively. Big data plays a crucial role in artificial intelligence by providing the necessary information for machine learning algorithms to analyze patterns, make predictions, and enhance decision-making processes.
