Network file system is one of the file systems supported by FreeBSD, also known as NFS. NFS allows a system to share directories and files with other systems on the network. By using NFS, users and programs can access files on remote systems just like local files.

The following are the most obvious advantages of NFS:

1. The local workstation uses less disk space, because ordinary data can be stored on one machine and accessed through the network.

2. Users don't have to have a home directory on every machine on the network. The home directory can be placed on an NFS server and can be used anywhere on the network.

3. such as floppy drive, CDROM, Zip? A storage device that other machines on the network can use. This can reduce the number of removable media devices in the whole network.

NFS has at least two main parts: server and client (or more). The client remotely accesses the data stored on the server. In order to work properly, some processes need to be configured and run.

NFS has many practical applications. Here are some common examples:

1. Multiple machines * * * share a CDROM or other devices. This is cheaper and more convenient for installing software in multiple machines.

2. In a large network, it may be convenient to configure a central NFS server to place all users' home directories. These directories can be exported to the network, so that no matter which workstation users log in to, they can get the same home directory.

3. Several machines can have a common /usr/ports/distfiles directory. In this way, when you need to install port on several machines, you can quickly access the source code without downloading it on each device.

Note: NFS was developed by Sun Microsystems. It is the NFS port of the network operating system: the channel for file \ data interaction with other devices.
