NANOG: North American Network Operators'Group; (see NANOG).
NAP: Network Access Point; a public networkexchange facility where Internet Service Providers (ISPs) can connect withone another in peering arrangements. The NAPs are a key component of theInternet backbone because the connections within them determine how trafficis routed. They are also the points of most Internet congestion.

NetBIOS: Network Basic Input/Output System;An IBM-developed(initially for IBM'sSytek PC LANprogram) standard software interface (API)to a network adapter. Has become a standard interface supported (eithernatively or with an additional layer of software) by most network operatingsystems to permit PCapplication programs to communicate directly with other PCsat the transport layer.
When the NetBIOS software is loaded, it broadcasts its proposed (upto 15-character) name to all other stations to
ensure that it will have a network-unique name.
NetBEUI: NetBIOSExtended User Interface; A nonroutable LANprotocol. An extension to NetBIOS.Used for IBM'sOS/2-based LANManager and Microsoft's LANManager and Windows for Workgroups.
NetBEUI (and NetBIOS,on which it is based) is nobody's favorite protocol (small packet and windowsize, nonroutable,
not open), so Microsoft has selected WinSock as its choice for preferredcommunications API.

NTSC: National Television Standards (Systems)Committee; USA video standard with image format 4:3, 525 lines, 60 Hz and4 Mhz video bandwidth with a total 6 Mhz of video channel width. NTSC usesYIQ NTSC-1 was set in 1948. It increased the number of scanning lines from441 to 525, and replaced AM-modulated sound with FM.
