Linux
An open source implementation of UNIX.
LLC
Logical Link Control. An additional data link layer protocol which 
operates on top of the MAC protocol defined in the original Ethernet 
standard (the "Blue Book").
LPD
The Line Printer Daemon is a protocol for transferring print jobs between 
hosts. This is the recommended method for UNIX/Linux systems, but 
some System V versions do not support LPD.
Logical Printer
A logical printer acts as a filter between the network and the physical 
printer. It appears to the user as a normal printer with additional 
characteristics. For example a UNIX/Linux workstation may only send a 
line feed (LF) to a shared printer that needs carriage return (CR) and LF. 
The logical printer can solve this problem by adding a CR whenever a line 
feed is detected.
NCP
NetWare Core Protocol. Network clients use the NCP to request services of 
servers, and servers use NCP to provide services, such as file and print 
services.
NDPS
Novell's Distributed Printing Services. 
NDS
NetWare Directory Services. A hierarchical data base that manages 
NetWare network resources such as servers and volumes.
NetBIOS/NetBEUI
Network Basic Input Output System, a network protocol with special 
functions for local area networks. NetBIOS Enhanced User Interface is an 
enhanced version of NetBIOS.
NetWare
An operating system for local area networks.
PCL
Printer Control Language — a set of command codes used when printing. 
A PCL driver is a small program that works between the operating system 
and the printer.
Peer-to-Peer Printing
When selecting Peer-to-peer printing, all print jobs are sent directly to the 
print server, rather than through a file server (client/server).
PEM
Privacy Enhanced Mail. 
RARP
Reverse Address Resolution Protocol. A TCP/IP protocol used for 
downloading IP addresses in UNIX/Linux networks. It requires a RARP 
daemon on your system, and only operates within a single network 
segment. A request made to an active RARP daemon initiates a search of
