What is a Hard Disk? And Facts!
It is a data storage device. It is used for storing and receiving data using rotating disks called platters coated with magnetic material.
It stores the data permanently. Also it retains its data even when powered off. The casing of the hard disk is air tight so nothing can get in or out! Hard disks are more faster than floppy disks.
Hard drive consists of the following components: The head actuator, read/write actuator arm, read/write head, spindle and platter. As seen below.
