(Leuciscus idus), also golden eye, a fish of the family Cyprinidae. The body length is up to 70 cm, and the weight, up to 2.5 kg (rarely 6–8 kg). The back is dark, and the underpart, silvery; all the fins are reddish. The ide is distributed in Europe, inhabiting rivers, lakes, and reservoirs; it is also found in the brackish waters of the gulfs of Bothnia and Finland. It attains sexual maturity in the third to fifth year of life. It spawns in April or May in shallows. The fertility is about 114,000 eggs. The ide feeds on insects, mollusks, worms, and algae. It is an object of both commercial and sport fishing. A domesticated form of ide, the orfe, is bred on fish farms.


(1) (Integrated Development Environment) A set of programming tools for writing applications (source code editor, compiler, debugger, etc.), all activated from a common user interface and menus. IDEs are standard procedure for program development. See Eclipse, compiler and debugger.

(2) (Integrated Drive Electronics/Intelligent Drive Electronics) A hardware interface for hard drives and CD/DVD drives. Introduced in 1986 with 20 megabytes of storage, IDE became the standard, with storage growing to hundreds of gigabytes. Officially an Advanced Technology Attachment (ATA) device (evolving from the AT bus), IDE's primary contribution was building the controller into the drive itself, requiring only a simple circuit on the motherboard. The ATA Packet Interface is the version for optical and removable drives (see ATAPI). Also known as "Parallel ATA" (PATA), IDE/PATA was superseded by Serial ATA (see SATA).

Master and Slave
Two IDE drives share one cable and are configured as master and slave. Out of the box, drives are set to master, and switching jumper pins makes them slaves.

Myriad Names Over the Years
The following mean the same thing: IDE, ATA, IDE/ATA, EIDE, EIDE/ATA, Fast/ATA and PATA. Using a 100 MB/sec example, drives went by "ATA-100," "Ultra ATA-100," "DMA-100" or "Ultra DMA-100." For detailed specifications, see PATA/SATA specifications. See Cable Select, SMART HDD, hard disk interfaces and SATA.

PATA Vs. SATA Cables
IDE/PATA cables took up a lot of room inside the case and impeded air flow. Motherboards had 40-pin sockets for optical drives and 80 pins for hard drives.

Fault Tolerant IDE
In the late 1990s, Arco was first to provide RAID 1 (mirroring) with "inexpensive" IDE drives rather than SCSI. This drive bay card plugged into the motherboard, and cables went to two drives (see RAID). (Image courtesy of Arco Computer Products, Inc.,

0 specification and provides complete ATA-66 Ultra DMA compatibility in an extremely compact and cost effective silicon solution.
Standard features include Intel(R) Pentium(R) III processors from 600 to 866 MHz with 256 KB advanced transfer cache and 133 MHz front-side bus, up to 1 GB(3) of PC700 or PC800 RDRAM, EIDE ATA-66 hard drives or Ultra/160 SCSI hard drives, and up to 16 MB of RAM integrated into the 4X advanced graphics port (AGP) enabling exceptional graphics performance and visual quality for today's multi-media and Web-based applications.
In addition to the AK72's north bridge set support of Virtual Channel Memory (VCM), its south bridge chipset uses the VT82C686A, which supports ATA-66, 4 USB ports, AC97Audio, as well as AMR and Hardware Monitor.

The Dx5000 is based on Intel's Pentium(R) III processor and the Intel 840 workstation-class chipset, and supports numerous next-generation technologies including RAMBUS memory, the faster 133MHz front-side bus, AGP Pro graphics, and the ATA-66 hard drive standard.
Designed with the Intel 840 chipset, the IntelliStation M Pro can include up to 1 gigabyte of high-performance Rambus ECC memory, 4X AGP capable of 1 gigabyte-per-second transfers, and a high-speed ATA-66 disk drive interface.
The new IntelliStation also features a high-speed ATA-66 disk drive interface -- again, double the bandwidth of previous models between disk drive and system memory -- speeding interaction with files stored on the hard drive.
