CPU usgae, disk I/O, network performance, etc., are part of server performance.
Explain the access mechanism of a Magnetic disk. How is this access mechanism different in RAID level 5?
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 primary storage unit of a computer
It is the magnetic elements in a magnetic disk that are used to store information.

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.
No. Disk caching improves hard-disk performance by anticipating data needs.

Its called a floppy disk.
Magnetic storage is used on hard drives and floppy disks. Sectors of the disk are charged magnetically and are easily changed later. Optical storage uses a laser to read data. On a cd/dvd, the laser picks up tiny marks made starting in the center and rotating outward.
