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. An Itanium word is also 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
