Detailed explanation-1: -Non-volatile memory is a term used to describe any memory or storage that is saved regardless of the power to the computer is on or off. The best example of non-volatile memory and storage is a computer hard drive, flash memory, and ROM.
Detailed explanation-2: -These disks spin extremely fast (typically at either 5400 or 7200 RPM) so that data can be accessed immediately from anywhere on the drive. The data is stored on the hard drive magnetically, so it stays on the drive even after the power supply is turned off.
Detailed explanation-3: -How is data stored on a hard disk? Data is stored on a hard drive in binary code, using 1s and 0s. The information is spread out on the magnetic layer of the disk(s) and are read or written by the read heads that ‘float’ above the surface thanks to the layer of air produced by the ultra fast rotation of the disk.
Detailed explanation-4: -A computer hard disk drive (HDD) is a non-volatile data storage device. Non-volatile refers to storage devices that maintain stored data when turned off. All computers need a storage device, and HDDs are just one example of a type of storage device.
