The first discs that were made for computers were made from a thin material that bent easily. These were referred to as floppy disc then a smaller disc with a hard plastic cover was brought out to replace this which was originally meant to be referred to as a hard disc, however at around the same time the discs that computers ran on were also looking for a name and these ended up being called the hard disc and the new rigidly encased discs went back to being referred to as floppy discs.
A hard disk is a Sequential Access Memory device or SAM
Magnetism is used to operate the fan motors and the disk drive motors as well as operating the "voice coil" that causes the disk read/write heads to move. The surfaces of the hard disk "media" is magnetized to represent data. The hard disk read/write heads are nothing more than small electromagnets and as the heads move across the spinning disk media, magnetic data is sent or received by the disk heads. Older computers used a magnetic "core" to store data. That's the origin of the term, "core memory". With the decrease in cost ind incredible speed of transistor based memory, nobody uses magnetic core any more.

The hard disk is a device which attached in a CPU where data , program ,and folder are being stored .
In the hard disk slot, I think.
No, it is an optical disc. A hard disk is defined as a device that stores data on spinning magnetic platters. Although a CD is 'hard' (rigid) as opposed to the flexible inside of a floppy disk, that does not classify it as a hard disk.
Disc = DVD or CD or Hard disk?? If its a DVD or CD then the chances are it has been formatted incorrectly. If its a hard disk then it probably has not been partitioned correctly or the disk partition is damaged, or the drive has not been formatted correctly
the right place on the hard disk has to be found, then the read/write head must be placed there, then the sector (a small part of the hard disk) is read or written, if it's read, the data is moved into the memory, maybe by the DMA (Direct Memory Access) Controller. Is it's a write operation, the data must first be given to the Hard Disc Controller.
"Disc" refers to optical media, such as CDs or DVDs. "Disk" refers to magnetic media, such as hard drives. So the answer depends on which drive you are referring to; most have both an "optical disc drive", and a "hard disk drive".

The IDE interface is limited to 528 megabytes hard disk capacity
>> some are cds, hard disk, floppy disc, flash drives
Track on afloppy disc
Yes, it takes longer to load from a floppy disk.
A hard disk can be either internal or external and one can use it to save files. The parts of a hard disk are the disk case, spindle, disk platter, actuator and the read-write arm.
