UDDI registry <UDDI registry>

Reading: U D D eye registry
Field:
WWW > Web service > UDDI registry

The database in order to search Web service with UDDI.

The information which is registered to UDDI registry is described by XML, is divided into four categories broadly by the classification. Registers the name of the enterprise which offers Web service and ahead etc communicating the “white page”, registers the type of industry type and service the “yellow page”, registers the technical information of Web service the “green page”, registers the specification of Web service “tModel” that is.

As for enterprise, following to the prescribed form which is decided, by the fact that it registers these items of information to UDDI registry, it is possible to release Web service to UDDI. As for UDDI registry the IBM corporation and the Microsoft corporation, the Hewlett-Packard corporation and the SAP corporation etc release gratuitously with the respective sight, to exchange the data mutually, in order for contents to agree, are adjusted.

UDF

Reading: U D f
Full spelling: Universal Disk Format
Field:
Storage > optical disk > DVD > UDF

One of the format for the optical disk which does not depend on OS. It is proposed by the economic organization OSTA regarding the optical disk, it is standardized by ISO and ECMA. It is adopted for DVD and CD-RW.

UDLR

Reading: U D l earl
Full spelling: Uni-Directional Link Routing
Field:
Network technology > network control > UDLR

The routing system which is represented in the satellite circuit, uses type direction telecommunication network. As for Internet technology 1 these circuits cutting bidirectionally with communication because it is designed, as prerequisite to do communication with type direction network, individual routing technology becomes necessary. By the fact that UDLR is used low speed request is transmitted with the bidirectional circuit, the operation that high speed that data is received from the type direction circuit, becomes possible. UDLR is standardized with RFC 3077.

UDMA <Ultra ATA>

Alias:
UATA, ATA-33, Ultra ATA/33, Ultra DMA and DMA-33
Field:
Personal computer > I/O > IDE/ATA > UDMA

IDE which the Quantum corporation and the Intel corporation announced in 1996, connect the personal computer and the storage unit of the hard disk and the like (ATA) extended specification of standard. In the succession specification of EIDE which is standardized as ATA-2, it was standardized in 1998 as ATA/ATAPI-4 with ANSI. The highest data rate is 33MB/s. The Quantum corporation calls Ultra ATA, but there are also times which the Intel corporation calls “Ultra DMA”, is called ATA-33 or DMA-33 etc to in addition to.

UDMA/100 <Ultra ATA/100>

Alias:
UATA/100, ATA-100, Ultra DMA/100 and DMA-100
Field:
Personal computer > I/O > IDE/ATA > UDMA/100

Extended specification of IDE (ATA) standard which the Quantum corporation and the Intel corporation announced in 2000, connect the personal computer and the storage unit of the hard disk and the like. Also “Ultra DMA/100” is called. Transfer rate being maximum, has reached 3 times that 100MB/s and Ultra ATA (/33). The connector uses those of 80 pins which are used even with Ultra ATA/66. Downward compatibility is guaranteed, can connect also the hard disk of Ultra ATA specification and EIDE specification. The schedule where by the way the formal calling with “Ultra DMA Mode 5”, formally is standardized with ATA-6 which presently is in the midst of deliberating with ANSI as portion of ATA standard.
