Detailed explanation-1: -ROM information can be easily updated. Data in ROM is non-volatile, that is, it remains there even without electrical power.
Detailed explanation-2: -Why ROM Is Non-Volatile? Read-only memory is a non-volatile storage solution. This is because you cannot erase or modify it when the computer system is turned off. Computer manufacturers write codes on the ROM chip, and users cannot alter or interfere with it.
Detailed explanation-3: -Read only memory that is ROM has some characteristics which make it useful. Those characteristics are data in ROM is nonvolatile, that is it remains there even without electrical power. it can store data for a long period of time.
Detailed explanation-4: -Because ROM is read-only, it cannot be changed; it is permanent and non-volatile, meaning it also holds its memory even when power is removed. By contrast, random access memory (RAM) is volatile; it is lost when power is removed. The use of the similar term “non-volatile memory” is applicable here (more on that later.)
