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.
RIP (Raster Image Processor)
The hardware and/or software functions of a printer that convert vector graphic
descriptions from a computer into raster graphic images that can be printed.
SMB
Server Message Block. A protocol that provides file and printer sharing over a network for
Windows computers.
Source Routing
Normally, a host has no control over the route taken by a packet it sends. Source routing is
a technique whereby the sender of a packet can specify the route that a packet should
take through the network to its destination.
Spooling
Simultaneous Peripheral Operations On-Line. Spooling means putting jobs in a buffer,
which is a special area in memory or on a disk. Because devices access data at different
rates, the buffer provides a waiting station where the data can wait until the device for
which it is meant is ready to access it.
Subnet Mask
SUBNETwork mask. The method used to determine which subgroup, or subnet, an IP
address belongs to on TCP/IP networks, all devices whose IP addresses have the same
prefix would belong to the same subnet. Dividing a network into subnets is useful for both
security and performance reasons.
