A zettabyte (ZB) is a unit of digital information storage that equals one sextillion bytes, or $10^{21}$ bytes. As the volume of data generated by various sources, including IoT devices, social media, and online transactions, continues to grow exponentially, the concept of zettabytes has become increasingly relevant in discussions about big data and artificial intelligence. AI models rely heavily on vast datasets for training, and managing, processing, and analyzing data at the zettabyte scale presents significant challenges. Understanding and working with zettabytes is crucial for AI practitioners to effectively harness the power of big data, enabling advancements in analytics, machine learning, and predictive modeling.
