A CDE Definition
Enhancements to the ATA-3 specification that increased transfer rates to 33 Mbytes/sec. See IDE.
(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 Also known as "Parallel ATA" (PATA), IDE/PATA was superseded by Serial ATA (see SATA).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.
