What services does nfs provide?

The service provided by nfs is "shared service". NFS allows a common file system to be shared among multiple users and provides the advantages of data centralization to minimize the storage space required. NFS can be used for remote access and sharing of network files in different types of computers, operating systems, network architectures and transmission protocol operating environments.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

The service provided by nfs is "shared service".

NFS (Network File System) is one of the current mainstream heterogeneous platform shared file systems. Mainly used in UNIX environment. First developed by Sun Microsystems, it now supports file sharing through the network between different types of systems. It is widely used in heterogeneous operating system platforms such as FreeBSD, SCO, and Solaris, allowing one system to share directories and files with others on the network. . By using NFS, users and programs can access files on the remote system just like local files, so that each computer node can use online resources as conveniently as local resources. In other words, NFS can be used for remote access and sharing of network files in different types of computers, operating systems, network architectures and transmission protocol operating environments.

NFS works using a client/server architecture, consisting of a client program and a server program. The server program provides access to the file system to other computers in a process called output. When the NFS client program accesses the shared file system, it "transports" them from the NFS server. Files are usually transferred in blocks. Its size is 8KB (although it may split operations into smaller sized shards). The NFS transfer protocol is used for file access and sharing communication between servers and clients, allowing clients to remotely access data stored on storage devices.

Features:

(1) Provide transparent file access and file transfer;

(2) Easy to expand new resources or software without changing existing ones Working environment;

(3) High performance and flexible configuration.
