Explanation:
NIS+ is a directory service developed by Sun Microsystems to replace
its older NIS (Network Information Service). It is designed to eliminate the need
for duplication across many computers of configuration data such as user accounts,
host names and addresses, printer information and NFS disk mounts on individual
systems, instead using a central repository on a master server, simplifying system
administration. NIS+ client software has been ported to other Unix and Unix-like
platforms, notably Linux.
