WINS
routed environment. A WINS server handles name registration, queries, and release
version updates (RVUs). See also IP address.
WINS. See Windows Internet Name Service (WINS).
word. An instruction-set-defined unit of memory that corresponds to the width of registers
and to the most common and efficient size of memory operations. A TNS word is
2 bytes (16 bits) wide, beginning on any 2-byte boundary in memory. A MIPS RISC
word is 4 bytes (32 bits) wide, beginning on any 4-byte boundary in memory.
work files. Temporary files created during system generation that serve as storage areas.
Work files are useful for debugging purposes after system generation. You can choose
to make specified work files permanent.
working directory. In the Open System Services (OSS) environment, a directory,
associated with a process, that is used in pathname resolution for relative pathnames.
worldwide name (WWN). A unique, 64-bit number assigned to hardware ports.
WORM. See write once, read many (WORM).
wormhole routing. A technique for reducing network latency in a router. Packet bytes are
immediately switched to the appropriate output port as soon as they arrive rather than
accumulated in a buffer until an entire packet is received. Contrast with store and
forward routing.
write once, read many (WORM). A media storage class in which data, once written, cannot
be erased or overwritten.
WWN. See worldwide name (WWN).
WWN zones. Similar to Ethernet virtual LANs (VLANs), WWN zones organize the cabling
and interactions between components in a storage and server system.
wye. A polyphase electrical supply where the conductors of the source transformer are
connected to the terminals in a physical arrangement that resembles the letter Y. Each
point of the Y represents the connection for a conductor at high potential. The angle of
phase displacement between each point on the Y is 120 degrees. The center point of
the Y is the common return point for the neutral conductor.
wye-delta. The interconnections between a wye source and a delta load.
X.21. A digital signaling interface recommended by the International Telecommunications
Union, Telecommunication Standardization Sector (ITU-T) that includes specifications
for data terminal equipment/data communications equipment (DTE/DCE) physical
interface elements, alignment of call control characters and error checking, elements of
the call control phase for circuit switched services, data transfer at or below 9600
bits/second, and test loops.
