Detailed explanation-1: -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-2: -Non-volatile memory (NVM) is a type of computer memory that has the capability to hold saved data even if the power is turned off. Unlike volatile memory, NVM does not require its memory data to be periodically refreshed. It is commonly used for secondary storage or long-term consistent storage.
Detailed explanation-3: -At its core, non-volatile memory is “byte addressable, ” random access memory (RAM) for computers that retains data even in the absence of power. Byte-addressable memories facilitate access to data at the individual byte level. Computer memory involves the “devices used to store information for use in a computer.”
Detailed explanation-4: -Non-volatile memory, on the other hand, is static. It remains in a computer even after a user switches it off. HDD and ROM are types of non-volatile memory.
Detailed explanation-5: -Data in RAM can be modified, erased, or read. Data in ROM can only be read, it cannot be modified or erased.
