What is the purpose of the Network File System (NFS)?

The purpose of the Network File System (NFS) is to provide transparent file access for clients. NFS allows users to access files on remote systems in much the same way they access local files, enabling different systems to interact seamlessly over a network. This means that a client machine can read and write files on a server as if they were local, making it particularly useful in environments where multiple machines need to access shared data without caring about the underlying physical storage.

The design of NFS abstracts the complexities of file location, allowing users to focus on file usage rather than where the files are stored. It enhances collaboration and simplifies file sharing within networks, especially in Unix and Linux environments where NFS is predominantly used. This transparency is key to its functionality, effective performance, and user experience.
