Detailed explanation-4: -HDFS employs a NameNode and DataNode architecture to implement a distributed file system that provides high-performance access to data across highly scalable Hadoop clusters. Hadoop itself is an open source distributed processing framework that manages data processing and storage for big data applications.
Detailed explanation-5: -Hadoop offers access to HDFS through a command line interface. The Syncfusion Big Data Studio offers Windows Explorer-like access to HDFS. It allows for common tasks such as folder and file management to be performed interactively.
