NetBIOS is an acronym for Network Basic Input/Output System. It is a program that allows applications on separate
computers to communicate within a Local Area Network (LAN), and it is not supported on a Wide Area Network (WAN).
The NetBIOS giving each computer in the network both a NetBIOS name and an IP address corresponding to a
different host name, provides the session and transport services described in the Open Systems Interconnection (OSI)
model.
NFS
NFS is an acronym for Network File System. It allows hosts to mount partitions on a remote system and use them as

storage over a computer network.
