What is the advantage of using a disk controller to control the hard disk?

The use of a separate disk controller frees the CPU to perform other tasks. In particular, the disk controller can manage DMA transfers, which otherwise would have to be done by the CPU. The disk controller also manages the movement of the disk head and reading or writing of the data on the disk. Again, without the disk controller, the CPU would be forced to perform these operations.

∙ 10y agoA disk controller is used to control disk drives. Such a controller adds disk drive ports/connectors to a system, and in a format compatible with whatever specific drive type. A floppy controller would control a floppy drive, a SATA controller a SATA drive, etc.

What is consists of a special purpuse chip and electronic circuits that control the transfer of ddata and instructions from a disk to and from the system bus and other components in the computer?
Disk controllers
How else could you do the job that the disk controller does?
if your refering to IDE or SATA controller mostly likely using IDE or Sata ports on the board else u could go external by USB disk controller is recognised in BIOS under an IRQ
What is the difference between disk duplexing or disk striping with parity?
Disk duplexing is where you're writing data to 2 or more disks, with each disk using its own controller. If one disk fails, the other disk continues to operate with no data loss. Even if you lose the disk controller, it is not a problem since you're using a separate controller for the other disk. It is considered an variation of RAID 1 disk mirroring. Disk striping does not duplicate data as in disk duplexing. It writes (stripes) data across 3 or more disks but uses parity checking for each disk. If one disk fails, the other drives can recreate the data stored on the failed one. It is considered RAID 5 level.
What is the IRQ for the floppy disk drive controller?
By default, the IRQ for the floppy disk controller is IRQ 6.
If a disk drive becomes active the disk controller provides this information to the CPU over the bus?
This is most likely the Control Bus the will send a signal to the CPU that the disk drive became active. If you noticed, eveytime you insert a CD, in Windows, a dialog pops up asking the user what to do. This occurs because the controller for this device sends that signal through the Control Bus which interupts the CPU.
Which type of adapter card connects disk drives?
A Disk controller.
What controls the interface between the hard disk and the system bus?
disk controller
What are special purpose chips and electronic circuits that control the transfer of data instructions and information from a disk to and from a systems bus and other components in the computer?
This sounds like a disk controller and possibly an I/O port. A disk drive has to have a controller. The controller is connected to the system bus or the southbridge chip, and that is how it is connected to the rest of the system. The controller uses a driver to tell the operating system how to communicate with it.If you mean further back than that, then you may be referring to the chipset chips. There is a northbridge and a southbridge, and it is the southbridge that connects to the peripheral bus and to any disk controllers.
Which is not a type of disk controller?
CD-ROM
What are the advantages of using an SAS drive?
The advantage of using an SAS disk drive is that it SAS disk drives contain more space. They also improve the easy of maneuvering things around within files.
