Answer 1

Answer:

Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retrieve stored information even after having been power cycled. In contrast, volatile memory needs constant power in order to retain data. Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM, most types of magnetic computer storage devices (e.g. hard disk drives, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.[1]

Non-volatile memory can be classified as traditional non-volatile disk storage, or storage in non-volatile memory chips (Flash memory Storage) – EEPROM, SSD, NAND, etc.
