Q. Explain Integrated Disk Electronics Devices?
IDE devices are associated to PC motherboard by a 34-wire ribbon cable. Common drive used today for workstations has capacities of 40MB to 1000MB and rotation speed 7200RPM. Controller is embedded on disk drive itself. It is an interface between disk controller and an adopter located on motherboard. It has good access time of 20ms and data transfer rates of nearly 1Mbps under ideal conditions. Drives are reasonably low-priced. Latest version of IDE specification allows four IDE channels. Each one of them is capable of supporting two IDE devices.
