Glossary 321
Glossary
start bit Data bit used to signal
the start of a character being
transmitted in an asynchronous
communication mode.
station address A 12-digit
hexadecimal link-level address
used by the IEEE 802.3 protocol.
Every node on an IEEE 802.3
network has its own station
address.
stop bit 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 ifthe network
is part of an internetwork. The
word subnet is also a synonym for
intranet.
subnet mask Grouping of bits
that determines which bits of the
IP address will be used to define a
subnetwork. The subnet mask is
configured using the NMMGR
utility and specified in the same
format as an IP address.
SVC Switched Virtual Circuit.
Path through an X.25 network
that is established at call set-up
time.
switching See DTC switching.
Switching user interface User
interface available when DTC
switching is enabled that allows
terminal users to choose the 900
Series HP 3000 computer with
which they want to establish a
communication link.
synchronous A mode of
operation or transmission
whereby a continuous data
stream is generated without
intervalsbetween 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 way
you tell the operating system
what peripheral I/O devices are
attached and what parameters
are required for system operation.
T
TCP See transmission control
protocol.
Telenet A proprietary public
data network in the USA.
TermDSM Terminal online
Diagnostic Support Manager. A
utility that provides diagnostic
services for DTC connections by
means of a series of commands
accessible through the SYSDIAG
