Frequent question: Why NFS protocol is used?

NFS, or Network File System, was designed in 1984 by Sun Microsystems. This distributed file system protocol allows a user on a client computer to access files over a network in the same way they would access a local storage file. Because it is an open standard, anyone can implement the protocol.

What is the purpose of NFS?

The Network File System (NFS) is a client/server application that lets a computer user view and optionally store and update files on a remote computer as though they were on the user’s own computer. The NFS protocol is one of several distributed file system standards for network-attached storage (NAS).

Why is Network File System Important?

Enables multiple computers to use the same files, so everyone on the network can access the same data. Reduces storage costs by having computers share applications instead of needing local disk space for each user application. Provides data consistency and reliability because all users can read the same set of files.
