Q – 8 Explain Hard Disk in detail.

A hard disk is a secondary storage device that is used to store data. It contains one or more plates in a circular form that rotates continually. These circular plates are coated with a magnetic material and stacked with space between them. The information is recorded on the surface of rotating disks by magnetic heads as tiny magnetic spots. Nowadays we have harddisks with a capacity of terabytes.
