time factor (TF)
time factor (TF). A number assigned to a line, path, or route to indicate its efficiency in
transporting data. The lower the time factor, the more efficient the line, path, or route.

TLB. See translation lookaside buffer (TLB).
TMF subsystem. See Transaction Management Facility (TMF) subsystem.
TNS. HP computers that support the HP NonStop™ Kernel operating system and that are
based on complex instruction-set computing (CISC) technology. TNS processors
implement the TNS instruction set. Contrast with TNS/R
.
TNS instructions. Stack-oriented, 16-bit machine instructions defined as part of the TNS
environment. On TNS systems, TNS instructions are implemented by microcode; on
TNS/R systems, TNS instructions are implemented by millicode routines or by
translation to an equivalent sequence of RISC instructions.
TNS mode. The operational environment in which TNS instructions execute. See also
accelerated mode
and TNS/R native mode.
TNS object code. The TNS instructions that result from processing program source code
with a TNS language compiler. TNS object code executes on both TNS and TNS/R
systems.
TNS object file. The object file created by a TNS compiler. The file contains TNS
instructions and other information needed to construct the code spaces and the initial
data for a TNS process.
TNS process. A process initiated by executing a TNS or accelerated object file.
TNS/R. HP computers that support the HP NonStop™ Kernel operating system and that are
based on reduced instruction-set computing (RISC) technology. TNS/R processors
implement the RISC instruction set and are upwardly compatible with the TNS
system-level architecture. Systems with these processors include most of the HP
NonStop™ servers. Contrast with TNS
.
TNS/R native mode. The operational environment in which native-compiled RISC
instructions execute. See also accelerated mode
and TNS mode.
Token-Ring ServerNet adapter (TRSA). A ServerNet adapter that provides a single line
from an HP NonStop™ S-series server to a token-ring network, allowing the server to
act as a station on the ring. The 3862 TRSA can be configured to support network
speeds of 4 megabits/second (Mbps) or 16 Mbps, and the media can be either
shielded twisted pair (STP)
or unshielded twisted pair (UTP).
topology. The physical layout of components that define a local area network (LAN), wide
area network (WAN), or ServerNet fabric. See also star topology
and tetrahedral
topology.
