PostScript PostScript is a page description language (PDL) developed by
Adobe Systems. It is an object-oriented language, meaning
that it treats images, including fonts, as collections of
geometrical objects rather than as bitmaps. PostScript is the
standard for desktop publishing because it is widely supported
by both hardware and software vendors.
Print driver See Driver.
Protocol The rules that control the transmitting and receiving of data.
Queue A place where jobs are stored temporarily, while they are
waiting to be processed. A print queue will hold several print
jobs.
RARP An abbreviation of Reverse Address Resolution Protocol. This
is a method for providing IP Addresses to nodes on a network.
When a node powers up, it broadcasts a RARP packet
containing its Ethernet Address. The RARP server receives
the packet and sends the IP Address back to the node.
Router A device that directs network packets to the segment of the
network for which the packet is intended, and excludes
packets that are not intended for a segment. Routers reduce
unnecessary network traffic and control access to segments of
the network.
SSDP An abbreviation of Simple Service Discovery Protocol.
SMB An abbreviation of Server Message Block. A protocol used to
to share files or printers on Windows OS.
SNMP An abbreviation of Simple Network Management Protocol. A
protocol used to help manage complex networks.
SPX An abbreviation of Sequenced Packet Exchange. SPX is part
of NetWare. It makes sure that packets are received in the
correct order and that there are no errors.
Subnet Mask There are approximately 4.3 billion different addresses in the
IP Address range of 000.000.000.000 to 255.255.255.255.
These addresses can be divided into smaller, and much more
manageable subnetworks, or subnets. The Subnet Mask
identifies which part of the IP Address contains the Subnet
Address and which part contains the host (or device) address.
TBCP Filter An abbreviation of Tagged Binary Control Protocol. This filter
is only available when PostScript is enabled.
