>fuzz, fuzzball
>fuzzball hardware
	The Fuzzball was an experimental TCP/IP package that ran on
	LSI-11's. Developed and maintained for the public good by Dave 
	Mills for several years. The first NSFnet was built out of
	Fuzzballs.

>GPS
	Global positioning System. A US military navigation satellite
	system; I think it contains about 27 satellites. Missiles can
	get their position to about 50 feet; but commercial customers
	can not get nearly as good accuracy: We did not want the Soviet
	missiles to benefit from our system !! The equivalent Soviet
	system is called Glonass.

>JvNC
>JvNC fuzzy
	John von Neumann Center for supercomputing.
	A fuzzball at that location.

>LORAN-C: an international time and location low frequency standard?
	A ground-based navigation system, similar to DECCA. Used by
	commercial aircraft and ships.

>MIT: Mass. Inst. of Technology?
	You got it.

>NEARNET
	New England Academic Research NETwork.

>net 128.175 friskers
>net 128.4 rascals
	Machines located on the networks with these addresses.

>norad (in context): ? a ____ site
	NORth American Air Defense. The command center of the USAF
	Strategic Air Command. An early pioneer in research of
	synchronizing distributed clocks.

>NSFNET NSS
	National Science Foundation Network Network Support System.
	A soon-to-be-built central monitoring site for NSFNET. I was
	surprised to hear that NSF might move their network operations
	away from Michigan.

>NTP
	Network Time Protocol.

>ntpdc
>ntpdc billboards
	A remote monitoring tool for NTP time server programs.

>oxide plow: informal description of disk head collecting disk scrape stuff

>pelt, pelting
	To beat on. To access/utilize a resource.

>primary server (in this context)
	The NTP synchronization mechanism allows for a primary peer
	group, to which other timers align themselves, in a manner
	similar to the tiered control of the network name service.

>Selective Availability
	The deliberate distortion of the commercial signal from the GPS
	satellites.

>umd1
	A host at University of MarylanD.

>UDP/TIME
	User Datagram Protocol encapsulated time protocol information.
