The term hard drive refers to the actual disks inside of the drive. however, the terms “Hard Disk”, “hard disk drive”, and “hard drive” are seen as referring to the same thing. It is a non-volatile memory hardware device. It is used to retrieve and store the data permanently on a computer.

It is a secondary storage device and consists of one or more platters. Using a magnetic head, data is written on these platters. All the computers have Hard Disks installed in them. These are used in storing the files for the operating system, software programs, and user’s personal files. If a Hard Disk is not installed on the computer, it cannot function.


Components of Hard Disk:

A Hard Disk consists of the following components: head actuator, read/write actuator arm, read/write head, spindle, and platter. There is a circuit board on the backside of Hard Disk, called a disk controller or interface board. It allows the Hard Disk to communicate with the computer.
