Hard Drive

A hard drive, also known as a hard disk drive (HDD), is a type of non-volatile storage device that stores digital data on magnetic disks. It is a secondary storage device used in computers to store and retrieve data. A hard drive consists of one or more disks, a motor to spin the disks, and a read/write head to access the data. It is a non-volatile memory, meaning that its contents are retained even when the power is turned off. Hard drives are commonly used in computers, laptops, and other devices to store operating systems, programs, and data.
