(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 Also known as "Parallel ATA" (PATA), IDE/PATA was superseded by Serial ATA (see SATA).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.,
