What does the acronym "HDFS" stand for?

HDFS stands for Hadoop Distributed File System, and it is a key component of the Hadoop ecosystem. HDFS is designed to store very large files across a distributed cluster of machines. The system is tailored to run on commodity hardware and provides high throughput access to application data.

One of the fundamental features of HDFS is its ability to handle the demands of big data by allowing for efficient processing and storage of data in a fault-tolerant manner. It achieves this by breaking up large files into smaller pieces (blocks) and distributing these blocks across multiple nodes in the cluster, which ensures that even if one node fails, the data is still accessible from other nodes.

The choice of "Hadoop Distributed File System" accurately reflects the primary functions and architecture of HDFS, making it the correct answer.
