ZCAV
Reading: [zetsutokiyabu]
Full spelling: Zone Constant Angular Velocity
Field:
Storage > structure > ZCAV |
Also ZBR you say. One of systems of the reading and writing in, the storage unit which such as CD utilizes the disk and MO. The system which from the inside perimeter divides the disk into several zones, inside that zone maintains angular velocity uniformly. It is the system which unites the both feature of The recent hard disk and the portion of MO, PD, Zip and Super Disk etc have adopted this system.

| One of systems of the reading and writing in, the storage unit which such as CD utilizes the disk and MO. The system which from the inside perimeter divides the disk into several zones, inside that zone maintains linear velocity uniformly. It is the system which unites the both feature of CAV and CLV. DVD-RAM and the like has adopted this system. |
ZIF
Reading: [jihu]
Full spelling: Zero Insertion Force socket
Field:
Microprocessor > design/structure > ZIF
|
It is the socket mechanism which can take out and put in the tip/chip with just raising and lowering the lever. It is utilized with the tip/chip where the pin of CPU and the like is many. It is possible to do installation and removal, without adding power to the part of the pin which is easy to break in addition the contact failure due to shallow thing it can prevent.

ZigBee
Reading: Jig B
Field:
Mobile > short range radio communication > ZigBee
|
One of short range radio communication standard for the home appliance. With Bluetooth and similar technology, also transmission distance is shorter than Bluetooth at low speed, but there is an advantage of calling to substituting cost low by economical electric power.
As for data rate with the highest as for maximum transmission distance being maximum in 30m and one network, you can connect 255 devices. Low electric power consumption with largest feature, transfer rate being slow, approximately 2 years it drives with alkaline single 3 dry cell battery 2, the prospect that it is applied to the distant control and the like of the home appliance which you are not concerned.
IEEE 802.15.4 is used in interface of physical layer, divides frequency zone of the same 2.4GHz band as IEEE 802.11b of wireless LAN standard into the channel of 16 and utilizes. In other things, in America 915MHz band, in Europe 868MHz available. At one time it was propelled, as radio communication standard for the home appliance it diverts the technology “of HomeRF,” it communicates with the protocol which is known as “HomeRF Lite”.

Zip
Reading: Zipf
Alias:
Iomega Zip
Field:
Storage > removable > Zip
|
The storage unit which the Iomega corporation developed, designates the disk as medium. 1995 March it was sold. The capacity per 1 100MB and is large, but there is no compatibility of other memory medium such as floppy disk. As for the even seek time of drive as for 29ms and data rate it is America it has spread on the center drive low to being price partly due. In connection with the personal computer SCSI and IDE (EIDE) being also the drive which other things and the parallel port can be used a special feature. The personal computer to which the Compaq Computer corporation and the Hewlett Packard corporation, IBM Japan, Ltd. and the Apple corporation etc build in Zip drive is sold. Also the superior interchangeable product of capacity 250MB is sold in 1998.
