FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The hard drive contains a spinning platter with a thin magnetic coating. A “head” moves over the platter, writing 0’s and 1’s as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0’s and 1’s.

Detailed explanation-2: -A platter is a circular magnetic plate that is used for storing data in a hard disk. It is often made of aluminum, glass substrate or ceramic. A hard disk drive contains several platters that are mounted on the same spindle.

Detailed explanation-3: -A disk read-and-write head is the small part of a disk drive which moves above the disk platter and transforms the platter’s magnetic field into electrical current (reads the disk) or, vice versa, transforms electrical current into magnetic field (writes the disk).

Detailed explanation-4: -A platter is one or more aluminum, glass, or ceramic disk coated in a magnetic media is located within a hard drive to store all your computer’s data permanently. When the computer is turned on, these platters begin to rotate at so many RPM (rotations per minute).
