Packet Signature
Encrypted signatures used when exchanging data packets to guarantee that a packet
really came from the computer that it claims to have come from. Packet Signature is
designed to prevent packet forgery and unauthorized Supervisor access to a
NetWare server.
PING
The PING command is used to test basic connectivity. By default, the Windows 95
version of PING sends four packets that are each 32 bytes long. Four packets are
enough to prove connectivity. To send a different number of packets, specify the
number with the -n command line argument. Send packets of a different length with
the -l argument. For example, the command ping -n 10 -l 1002 peanut.nuts.com
sends ten packets that are each 1002 bytes long.
Protocol
A set of rules that govern the transmission of data across a network. Examples of
protocols are FTP, DHCP, BOOTP, RARP, IPP, and TCP/IP.
Proxy server
A server that provides a cache of files available on remote servers that are slow or
expensive to access. The term “proxy server” normally refers to a World Wide Web
server that, on receiving a URL, tries to supply the requested file from its cache. If it
cannot locate the file there, the proxy server would bring it from the remote server and
also save a copy in its cache so that the next request can be obtained locally.
Queue Server mode
When the printer is used in NetWare’s queue server mode, all print server functions
are provided by the printer itself, and no other print server hardware or software is
required.
RARP
Reverse Address Resolution Protocol. A protocol that associates a network adapter
address (MAC address) with an Internet Protocol (IP) address.
Raster
Raster graphics describes an image as a pattern of dots, compared to vector
graphics which represents an image as a geometrical formula. Each row of color dots
in the mosaic of color dots constitutes one raster graphic. In a printer, a raster graphic
is used as the master image from which a page is printed, because the image can be
transferred to paper by printing one raster at a time.
Raw
This is a print application used with Windows 2000/XP. It can print at higher speeds
than LPD.
