Glossary
SNMP Simple Network
Management Protocol. An
industry standard, for managing
networked computers in a
multi-vendor environment.
SNP Synchronous Network
Processor card; an alternative
name for an X.25 board.
spooled device A printer that is
accessed through the MPE/iX
spooling facility. The spooling
facility allows a nonsharable
device to be shared among several
users by temporarily storing
output data on disc and managing
the selection of output spool files
destined for the spooled device.
start bit A data bit used to signal
the start of a character being
transmitted in an asynchronous
communication mode.
station address A link-level
address used by the IEEE 802.3
protocol that is assigned to every
node on an IEEE 802.3 network.
stop bit A data bit used to signal
the end of a character being
transmitted in an asynchronous
communication mode.
store-and-forward A technique
in which messages are passed
from one node to another in a
network to reach their
destination. Point-to-point
networks use the
store-and-forward technique to
transmit messages.
subnet Another name for a
network, especially if the network
is part of an internetwork. The
word subnet is also a synonym for
intranet.
SVC Switched Virtual Circuit.
The path through an X.25
network that is established at call
set-up time.
switching See DTC switching.
Switching User Interface The
user interface available when
DTC switching is enabled that
allows terminal users to choose
the MPE/iX computer with which
they want to establish a
communication link.
synchronous A mode of
operation or transmission in
which a continuous data stream
is generated without intervals
between characters. The data
stream is synchronized by clock
signals at the receiver and
transmitter. As a result, fast
transmission speeds (above
9600 bps) are attainable.
SYSGEN The software program
that allows you to configure the
operating system on HP 3000
Series 900 computers.
system configuration The
method for telling MPE/iX which
peripheral I/O devices are
attached to the DTC and which
parameters are required for
system operation.
