FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The term backing storage refers to any non-volatile data storage that will retain a computer’s data, even after the computer is powered off. Common types of backing storage devices are hard drives, SSD, external hard disk drives, optical media such as CD or DVD, and flash media such as thumb drives and memory sticks.

Detailed explanation-2: -What are non-volatile storage examples? Three common examples of NVS devices that persistently store data are tape drives, HDDs and SSDs. The term non-volatile storage also applies to the semiconductor chips that store data or controller program code within devices such as SSDs, HDDs, tape drives and memory modules.

Detailed explanation-3: -non-volatile memory include read-only memory (see ROM), flash memory, most types of magnetic computer storage devices (e.g. hard disks, floppy discs and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards.

Detailed explanation-4: -ROM (Read Only Memory) is nonvolatile: data stored in ROM maintains integrity after loss of power. A computer Basic Input Output System (BIOS) Firmware is stored in ROM.

Detailed explanation-5: -There are mainly five types of nonvolatile memory technology: Flash memory, ferroelectric random-access memory (FeRAM), magnetic random-access memory (MRAM), phase-change memory (PCM), and RRAM.
