HDFS, or Hadoop Distributed File System, is a distributed file storage system designed to handle large volumes of data across clusters of computers. It is a core component of the Apache Hadoop ecosystem and is known for its scalability, fault tolerance, and high throughput. HDFS divides large files into smaller blocks, replicates them across multiple nodes in a cluster to ensure data durability, and provides a framework for processing and analyzing big data in a distributed fashion.
