What are the parts of the hard 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.
What is disk caching?
Disk caching improves the time it takes to read and write from a hard drive. A disk cache is essentially RAM that is built into your hard drive.
What influences the computer's performance?
cpu power, hard disk read/write capability, RAM read/write, software programmation
What is disk drive?
A disk drive is a device that computers can use to read and write information on computer disk. An example of one is the hard disk drive.
All the read write heads of a hard disk are controlled by a?
Its is controlled by the "Actutator arm"
What must happen before any data can be read or written on a hard disk?
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.
What is the term used to describe what happens when the read-write head of a hard disk touches the surface of the disk platter?
HDI - Head to Disk Interference.
What is inside a hard disk on the computer?
Ferrite or cobaltite crystals are within a hard disk.
Does the read write heads on a hard disk drive actually touch the surface of the disk?
no, the head not touching the surface of the hard disk. If it touch the great chance of data may be lost. only the head of floppy disk is touch the surface of the disk.
Can the hard disk of today used as input or output explain?
Since you can both read from (input) and write to (output) a hard disk, it is considered both an input and an output device.
What is the name of the card that controls read write head and motor in the hard disk?
The card that controls the read/write head and motor in a hard disk is called the Disk Controller or Hard Disk Controller (HDC). It manages data flow between the drive and the computer, ensuring accurate reading and writing of data on the disk platters. The controller also handles tasks like error correction and the translation of logical block addresses to physical locations on the disk.
Hard Disk is a type ROM?
HDD is not Read Only Memory. Rather it is a Read-Write memory. So HDD is not the ROM.
