Working principle of a hard disk controller

A hard disk controller (HDC) is an electrical component within a computer hard disk that enables the processor or CPU to access, read, write, delete and modify data to and from the hard disk. Essentially, an HDC allows the computer or its processor to control the hard disk.

11. Integrated Drive Electronics(IDE) Integrated Drive Electronics A type of hardware interface widely used to connect hard disks, and optical disks to a PC.  A standard interface for connecting a motherboard to storage devices such as hard drives and CD-ROM/DVD drives

12. ATA AT Attachment (ATA) is a standard interface for connecting storage devices such as hard disks and CD-ROM drives inside personal computers. Serial ATA is a computer bus technology designed for transfer of data to and from hard disks and optical drives.

13. Small Computer System Interface Is a set of standards for physically connecting and transferring data between computers and peripheral devices. SCSI is most commonly used for hard disks, but it can connect a wide range of other devices, including scanners, printers, and optical drives etc.
