Yellow Pages

    (NIS) Sun Microsystems' Yellow Pages
   (yp) client-server protocol for distributing system
   configuration data such as user and host names between
   computers on a network.

   Sun licenses the technology to virtually all other Unix
   vendors.

   The name "Yellow Pages" is a registered trademark in the
   United Kingdom of British Telecommunications plc for their
   (paper) commercial telephone directory.  Sun changed the name
   of their system to NIS, though all the commands and functions
   still start with "yp", e.g. ypcat, ypmatch, ypwhich.

   Unix manual pages: yp(3), ypclnt(3), ypcat(1), ypmatch(1).

	NISI. This word is frequently used in legal proceedings to denote that 
something has been done, which is to be valid unless something else Shall be 
done within a certain time to defeat it. For example, an order may be made 
that if on the day appointed to show cause, none be shown, an injunction 
will be dissolved of course, on motion, and production of an affidavit of 
service of the order. This is called an order nisi. Ch. Pr. 547. Under the 
compulsory arbitration law of Pennsylvania, on the filing of the award, 
judgment nisi is to be entered: which judgment is to be as valid as if it 
had been rendered on the verdict of a jury, unless an appeal be entered 
within the time required by the law.
