• SCSI-2: Same as SCSI-1, but uses a 50-pin connector
instead of a 25-pin connector, and supports multiple
devices.
• Ultra SCSI: Uses an 8- or 16-bit bus, and supports data
rates of 20 or 40 MBps.
• Ultra2 SCSI: Uses an 8- or 16-bit bus and supports
data rates of 40 or 80 MBps.
• Ultra3 SCSI: Uses a 16-bit bus and supports data rates
of 80 or 160 MBps.
• Ultra160 SCSI: Uses a 16-bit bus and supports data
rates of 80 or 160 MBps.
SME. System Managed Encryption.
SNMP. Simple Network Management Protocol. Used
by network management systems to monitor
network-attached devices.
SNS. Sense.
SNTP. Simple Network Time Protocol. Used to
synchronize the clocks of network-attached devices.
special feature. A feature that can be ordered to
enhance the capability, storage capacity, or performance
of a product, but is not essential for its basic work.
SPI. Security Parameters Index.
SR. Service representative, see also CE.
SRAM. Static random access memory.
SS. Status store.
SSL (Secure Sockets Layer). A set of cryptographic
protocols for secure communications on the Internet for
such things as web browsing, e-mail, Internet faxing,
instant messaging, and other data transfer. SSL allows
applications to communicate across a network in a way
designed to prevent eavesdropping, tampering, and
message forgery.
ST. Store.
standard feature. The significant design elements of a
product that are included as part of the fundamental
product.
START. Start maintenance.
subsystem. A secondary or subordinate system,
usually capable of operating independently of, or
asynchronously with, a controlling system.
SUPP. Support.
sync. Synchronous, synchronize. Occurring with a
regular or predictable time relationship.
system-managed encryption. Tape encryption is set up
implicitly through the IBM device driver.
T
tachometer, tach. A device that emits pulses that are
used to measure/check speed or distance.
tape cartridge. A container holding magnetic tape that
can be processed without separating it from the
container.
tape void. An area in the tape in which no signal can be
detected.
TCP/IP. Transmission Control Protocol/Internet
Protocol.
TCU. Tape control unit.
TH. Thermal.
thread/load operation. A procedure that places tape
along the tape path.
TM. Tapemark.
transport mode. End-to-end communications security
in which the end-point computers do the security
processing.
trusted certification. In cryptography, a trustworthy
certificate not registered with a Certificate Authority.
tunnel mode. Port-to-port communications security in
which security is provided to several machines by a
single node.
U
UART. Universal asynchronous receiver/transmitter.
unload. Prepare the tape cartridge for removal from
the drive.
utilities. Utility programs.
utility programs. A computer program in general
support of the processes of a computer; for instance, a
diagnostic program.
uv. Under voltage.
V
VOLSER. Volume serial number.
