NFS enables system administrators to share all or a portion of a file system on a networked server to make it accessible to remote computer users. Clients with authorization to access the shared file system can mount NFS shares, also known as shared file systems.

A network protocol for distributed file system.

Using this ,a user on the client computer can access the file on server side like as they are accessing locally.
