Disk interfaces employed in computers

Question

Briefly state about the various types of disk interfaces employed in computers?

Answer 1

There are different interfaces throughout that hard disks connect to the computer which are illustrated below:

1) Legacy Bit Serial Interfaces : They are the oldest form of interfaces that employed two cables to connect the disk to a controller. One cable was employed for data while the other is employed for control. Plus the above cables a power cable was as well required to supply power to the disk.

2) Modern Bit Serial Interfaces : In these kinds of interfaces the disk is connected to a host bus interface adapter employing a single cable. Besides this cable a power cable is as well used to power the drive. A number of modern bit serial interfaces: Serial ATA, Fiber Channel and SCSI.

3) World Serial interfaces : They are comparable to modern bit interfaces; these interfaces make employ of a cable for data and control. Some of the ordinary world interfaces: EIDE, IDE, SCSI and so forth.
