What connections are the IDE interface standards in PCs mainly used for?

#The IDE interface standard in PC is mainly used to connect the hard disk to the host.

IDE interface:

IDE interface (Integrated Drive Electronics) is an electronic integrated drive that integrates the "hard disk controller" and "disk body" in together with the hard drive. This technology integrates the disk body and the controller to reduce the number and length of hard disk interface cables, enhances the reliability of data transmission, and makes hard disk manufacturing easier.

Therefore, hard disk manufacturers no longer need to worry about whether their hard disks are compatible with controllers produced by other manufacturers. For users, the hard drive is also more convenient to install. The interface technology of IDE has been continuously developing since its birth, and its performance has been continuously improved. Its low price and strong compatibility have created a position that cannot be replaced by other types of hard drives.

The IDE interface is an interface jointly developed by Western Digital and COMPAQ Computer. Due to the continuous improvement of technology, the maximum transfer speed of the new generation Enhanced IDE (Enhanced IDE, referred to as EIDE) can be as high as 100MB/second (Ultra ATA/100)

Advanced Technology Attachment Specification (Advanced Technology Attachment)", referred to as ATA. IDE (Integrated Drive Electronics) is the general name for all existing ATA specifications. The ATA interface was first jointly developed by Compaq, Western Digital and other companies in 1986, and began to be used in desktop systems in the early 1990s. It uses a 40-core cable to connect to the motherboard. The original design could only support two hard drives, and the maximum capacity was limited to 504 MB.

The IDE interface is essentially a standard way to connect a storage device to a computer. And IDE is not the real technical name of the interface standard. Its original name was AT Attachment (ATA), indicating that the interface was originally developed for IBM AT computers.

Advantages of IDE interface: Low price, strong compatibility and high cost performance.

Disadvantages of IDE interface: Slow data transmission speed, too short cable length, and few connected devices.
