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: -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.)
Detailed explanation-3: -RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
Detailed explanation-4: -Data present in Read-Only Memory (ROM) is not volatile, it is permanent. Data will remain unchanged even when there is a disruption in the power supply.
