transient
transient. A short-duration, high-amplitude impulse that is imposed upon the normal voltage
or current.
translation lookaside buffer (TLB). A special-purpose cache, part of the RISC processor
chip, that is used in quickly translating virtual addresses to physical addresses. This
rapid translation is accomplished by remembering and reusing the translations of
recently referenced pages.
Transmission Control Protocol (TCP). A connection-oriented protocol that provides for
the reliable exchange of data between a sending and a receiving system. TCP
implements functions corresponding to the Open Systems Interconnection (OSI)
reference model Layer 4, the transport layer.
Transmission Control Protocol/Internet Protocol (TCP/IP). A set of layered
communication protocols for connecting workstations and larger systems in both local
area networks (LANs) and wide area networks (WANs). See also HP NonStop™
TCP/IP and Parallel Library TCP/IP.
tri-star topology. A network topology that uses up to three HP NonStop™ Cluster Switches
for each external fabric. External routing is implemented between the three star groups
of a ServerNet cluster. (A star group consists of the eight nodes attached to one set of
cluster switches.) The star groups are joined by two-lane links. Introduced with the
G06.14 release version update (RVU) of the HP NonStop ServerNet Cluster product,
the tri-star topology supports up to 24 nodes. See also split-star topology, star
topology, and layered topology.
Trivial File Transfer Protocol (TFTP). A protocol defined by Request for Comments (RFC)
1350. TFTP is used as a data link control (DLC) and diagnostic task.
TRSA. See Token-Ring ServerNet adapter (TRSA).
TSM. See Compaq TSM.
TSM client software. See Compaq TSM client software

TSM EMS Event Viewer Application. See Compaq TSM Event Viewer
.
TSM Low-Level Link Application. See Compaq TSM Low-Level Link.
TSM Notification Director Application. A component of the Compaq TSM client software.
The TSM Notification Director Application receives incident reports from an HP
NonStop™ S-series server, displays them, and allows you to take action or forward the
incident reports to your service provider for resolution. The TSM Notification Director
can be configured to run on a system console at all times, even when other TSM
applications are not being used.
TSM package. See Compaq TSM package.
TSM server software. See Compaq TSM server software.
