Which of the Following is Non Volatile Storage?

By Komal|Updated : July 15th, 2022

A type of computer memory known as non-volatile memory (NVM) or non-volatile storage can keep recorded data even when the power is turned off. Comparatively, volatile memory requires ongoing power to preserve data.

Flash memory storage, such as NAND flash, and solid-state drives are examples of non-volatile memory. Non-volatile memory is typically used to refer to storage in semiconductor memory chips that stores data in floating-gate memory cells made up of floating-gate MOSFETs (metal-oxide-semiconductor field-effect transistors) (SSD).

Answer - Non-volatile storage is used for secondary storage because it prevents data loss during power outages.

A type of non-volatile memory is ROM. Memory types that continue to function even after the power is switched off. While RAM is volatile, ROM is nonvolatile. This phrase frequently refers to the PC's CMOS memory, which houses the BIOS.

The contents of RAM, which is referred to as volatile memory because they are lost when the power is turned off, are kept even after the power is switched off. RAM is said to as volatile because it only exists temporarily. Since ROM is permanent memory, it is referred to as non-volatile memory.

Because the data in read-only memory (ROM) is not lost when a computer is shut down and restarted, it is not volatile. Read-only memory (see ROM), flash memory, the majority of magnetic computer storage media (such as hard discs, floppy discs, and magnetic tape), optical discs, and early computer storage techniques like paper tape and punched cards are all examples of non-volatile memory.
