A hard disk is a fixed storage medium used in computers and other electronic devices. A hard disk is used to permanently store data. It is a metal disk consisting of several rotating magnetic disks known as hard disks. These disks store data by changes in magnetic charge on the disk surface, and data is read and written using magnetic read/write heads that move over the magnetic disks. The hard disk is considered one of the basic types of storage in modern computers and electronic devices, thanks to its large capacity and relative speed in accessing data
