A computer hard disk drive stores and retrieves data efficiently by using magnetic storage technology. Data is written onto the disk using a magnetic head that creates tiny magnetic fields on the disk's surface. To retrieve data, the head reads the magnetic fields and translates them into digital information. The disk spins rapidly, allowing the head to access different parts of the disk quickly. This process enables the hard drive to store and retrieve data in a fast and efficient manner.
Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?
CPU usgae, disk I/O, network performance, etc., are part of server performance.
It's a track (a section of a magnetic disk, or a section of any given storage device that emulates a magnetic disk that uses the the LBA/CHS[Cylinder, Head, Sector]) that the computing device dedicates to store parity data (data to aid in error verification/correction for data that is stored on the disk).
Yes, there are some surprisingly strong magnets in the Hard Disk Drive. The read/write "head" also is an electromagnet, and the "platter" (spinning disk) is magnetized, but over all not very magnetic.
It is the magnetic elements in a magnetic disk that are used to store information.
computer use to magnetic disk which generation
magnetic disk
Digital information is stored in microscopic needles as part of the disk's magnetic coating.
In a way, yes. The material that makes up the "disk" in a floppy is Mylar, a magnetic substance. Data is stored on the Mylar disk in the form of magnetic charges.
A disk drive.
No. Disk caching improves hard-disk performance by anticipating data needs.
A sector
Yes, data is written to and read from a floppy disk using a magnetic read/write head that interacts with the magnetic coating on the disk. When writing data, the magnetic head aligns the magnetic particles on the disk surface to represent the information. When reading data, the head detects the magnetic orientation of the particles to retrieve the stored information.

magnetic tapes are cheaper
Its called a floppy disk.
