FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -Non-volatile (secondary) memory refers to storage that is permanent, meaning it is not altered when a device is turned on or off. Non-volatile memory has no need to be wiped or refreshed and has a higher storage capacity than volatile memory.

Detailed explanation-3: -The secondary storage is the non-volatile storage unit because the data is not lost when the power supply is dissipated. Primary memory is the volatile memory.

Detailed explanation-4: -Secondary storage, sometimes called auxiliary storage, is non-volatile and is used to store data and programs for later retrieval. There are many kinds of secondary storage, each with advantages and disadvantages. Most storage devices use either magnetic or optical storage media.

Detailed explanation-5: -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.
